EUNORAU 48v 500w Tongsheng Mid Motor Kit Review - $1k
Vložit
- čas přidán 25. 01. 2019
- The EUNORAU 48v 500w Tongsheng Mid Motor Kit is a surprisingly smooth torque sensing mid-drive kit, with waterproof connectors and a slim profile. The downtube battery pack keeps weight low and center on the frame, it can be charged on or off the bike and the plugin port is located away from the crank arms for protection. Thumb throttle offer power override at any level of assist, Full color display with easy read out and active energy use displayed. Additional work is required to install kits (or money if you work with a shop), wires usually cannot be internally routed, two bolt battery pack mount can be a challenge depending on the donor frame.

Awesome review thank God there are CZcamsr's like you to show us these kits before we kick out the money thanks alot much appreciated 👍
Superb review. All info is relevant to the average Joe. Excellent job. Appreciate it.
Luna Cycle In El Segundo, CA Is selling the Tongsheng mid drive in the 750w version and $899. with battery.
I thought I had to mount my battery upside down as well, but found that removing the panel on the battery mount revealed more mounting options through the heat sink. Not obvious, but if your mount looks like it has three screws and a bottom cover you may be able to do the same thing.
I love this kit 500w with 15ah Samsung battery. Have 2 kits tidily fitted.
My wife's Giant liv which she really wants to ride places now.
I have the same kit on a 2018 Giant Roam Disc hybrid and I fitted the bikes original larger 2 cogs 32 and 48 teeth with the adaptor. Used the guts of the ebrakes and fitted to my hydraulic set up because if you have your foot on the pedal stopped waiting to take off the motor will want to move.
I use the smaller gear to climb super steep hills with ease and on the flat stay in the 48 with the rear cassette 11t and easily sit around 40ks.
You still have to pedal to get the assist. (I left off the throttles) So it's great for my fitness as I am 65.
The pedal assist is outstanding and is so sensitive to input pressure on pedals.
Such a good bike for just over 2k AU!
Sounds really good. Hope you don't mind a few questions:
1. Is it easy making this work with hydraulic brakes? I am thinking of the magnet in the brake levers that cuts the motor out? How do you get that working with an hydraulic brake system?
2. Do you have any thoughts on whether you need a suspension front or a rigid front fork with this kit? Any thoughts on whether one is better than the other?
Thanks.
Great review, wish to see also how their 52v 750W motor performs but fitted on a much better bike, please review that motor as well, drive safe!
To get the space you need to fit the battery, use the upper screw mount on the bike and drill a hole
At the same distance as the mount, then find a screw that can screw into the frame to mount the battery holder.
That's what I did for mine & it works fine with no problems!
I have this kit 350w coaster brake version, works great so far, very smooth and natural biking experience. I don't need a car anymore :)
Thanks so much for this review--pity the major players have yet to roll out such conversion kits, but if these alternative kits are out there, they are certainly worthy of consideration. But wraps or covers for those exposed wires should be part of the package as wires and water don't particularly get along. And anyone who does "a little bit of mickey mouse" is my kind of mechanic :)
Battery mounting idea... I had the same issue so I removed the plastic cover from the bottom of the mounting base and drilled a hole in the metal to mount the battery then put the cover back. I also drilled an extra hole on the down tube and used a rivnut for an extra threaded mounting point. It started wiggling the screws loose so I used thread locker and now it’s all good.
Very well done review!
On the tsdz2 you don't need the brake cut offs - the motor stops when you stop pedaling - just more cable clutter.
Ditto, my kit did not even come with brake sensors.
@@deanhedin1615 I think they're mostly for folks who use the throttle exclusively. And/or if you set up the tail-light (I'll have to check mine when it gets here, but I think it dims/brightens the rear light with brake application if the lights are turned on, but I could be wrong on that)
If you needed to apply the brakes and tension the crank at the same time eg starting off, especially hill start, then you would need the cut off effect of brakes
I thought for a second I was on the wrong channel here when I saw your face Mikey, was thinking BMB has a new intro, anyway, great review as ever Mikey, hope to see more reviews from you. Best wishes great fella.
Thanks!
You can purchase stainless steel m5 rivets drill new holes further up the downtube should solve the problem
Totaly thru me off too for a second. . . he shoulda worn his helmetthe whole time. ;) I liked how he spoke and presented his info. I'm bummed how much the kit cost. I would like a bad ass kit for 500 but thats with no battery I'm sure so I guess its maybe average. . . hmmm. Idk. Happy biking.
@@rhysstatham7407 That's a good idea. I'll have to drill new holes if I use this bike for another conversion.
Thanks - lots of great info!
awesome review! I wonder if a smaller chain ring could be used.
Great Review. No I correct myself, excellent review.
Regarding the main power connector, On my conversion, I put an XT60 connector inside the cast aluminum box of the battery tray mount. This allows the battery tray to be separated from the motor's main power connector if you want to remove the tray. It's also somewhat protected from the elements though for a permanent setup, I would seal the cable entry to the tray box with silicon. You need some basic soldering skills to do this. -Dave Muñoz PS: nice video!
Many thanks , very useful
Rice rocket, car guy, spotted! Thanks for the comprehensive video. Entertaining the 52 volt kit, really wish my bbhsd’s had torque sensing.
I really like your reviews, didn't you use to work for some other site?
I'm going to need counseling after that review . Il give ye a thumbs up
Hi Thanks for the video, did you have issues with the clearance between the motor housing and the bottom of the bottom bracket where the rear brake/ rear derailleur / front derailleur cables run?
Tongsheng has the best throttles 👍🏽🚲💨
Hey! Great video, thank you! Forgive me if I missed it but does this kit come with "shift sensing" technology?
Not that I know of. I'm partial to shift sensing, myself.
@@nettoyageadriance
😀
No need for that, you just pause pedaling momentarily as you go through the gears as normal.
Have done 2500ks on my Giant hybrid with no issues, just lovin this kit.
I think tht would be nice to test Lingbei mid drive motor. Its new company owned by Bafang engineers. It has very high torque and has improved gears. The price for full kit 500W-750W48V is about 400$ incl fees.
If the torque sensing for this one can be ironed out, it would be competitive with the tongsheng. I was sold on the BBS02 or the HD but I think the Tongsheng has the best combo of features and seller / aftermarket / community support.
any long term review or update on reliability or issues with this installation ?
Hi, could you tell me if this motor works for someone who cannot put a lot of force into pedals? Can you get to topspeed or is it just slow going? Thanks. Also for the very clear video.
i have 42 volt batteries, would they be suitable on this kit or would there be a significant decrease in performance?
Man please review motor also what range you get ...battery specs stc. How comfortable is the ride.
GREAT REVIEW... What about the size of the kits bottom bracket torque sensor size (dimensions) to fit any bike?
The motor size fits a 68-73mm width
I just added the 750w motor to a steel frame road bike I have. Awesome so far. You can see on my channel.
Thanks for the video. I cannot get rid of my brake levers as they are for hydraulic brakes and they are also the shifters: RapidRise. What can I add to my levers to get the motor cutout? Aftermarket sensors available? Thanks!
I checked Aliexpress for more info on Eunorau offerings. I have a Samsung 48v battery from a rear hub conversion I did two years ago. I saw that a 48v 500 w / 36v 350 w kit without a battery was available. I have two questions: 1 - From my rear hub conversion I learned that the controller had to match the battery’s voltage. What I don’t know concerns the battery’s management system. Do you know if there could be compatibility issues? 2 - I want to add a mid drive to a Day6 Samson, which as Court can attest to is a long bike frame. I believe the cables need to be at least 14 inches longer than on a conventional bike like you converted. You showed that you folded the extra cabling. Do you think it was at least 14 inches? I really enjoyed this video and look forward to many. But I want to make sure that you know Court owns the phrases “I love that...” and “I appreciate...”.
lol, I've been making moves to trademark some phrases: "anyways anyways anyways!" and "as you can imagine".
I think the only length issue you'd have is with the speed sensor. I'll go measure the length of the cable and get back to you. I don't think it's long enough from my memory.
Just converted a Trek hybrid with the 36V kit. It is probably the best conversion kit available. Make sure you get the 850C display option.
Why 850c and not VLCD5 ?
@@grmar1494 Because the 850C display is better and you can upgrade the firmware.
No locking nut on the crank just the bracket with the spacers? and could of rotated motor to clear battery the right way up.drill a new hole and fit a rivnut to alter in triange position.
What if the spoke breaks losing the magnet piece. How about if you have a mag wheel? How will it work, or have they advanced the read out by now?
I had the same problem with the battery pack. my solution was to keep the battery in the original orientation, move the lowest battery tray slot to the upper-most cage-boss on the down-tube so there's one hard-point into the frame then 3d print some brackets to take the place of the water-bottle mounts. The 3D printed brackets are PETG and won't damage my aluminum frame. If this proves reliable, I'll post the STL files on thingiverse.
-Dave Muñoz
yes, please post the link on thingiverse or printables. that would be great! would help to post photos of the parts on the bicycle too. thanks!
Don't put the battery upside down. It's pretty easy to make a bracket to move it up a bit. My first one was simply a fender mount piece of steel that I reshaped in my vise.
Great. I did just get a specialized epic marathon over 10 years old. Tong shen seems like the best option. Im not willing to replace my hydraulic xtr brakes to get a brake sensor. If you let go of the throttle doesn't the engine go into free wheel? I don't fully understand why those brake sensors work.

Oppqpp
Hi there.good build.i had to mount my battery 🔋 upside down too but kuz of the shape of my battery it looks actually better than it would the proper way .I got the bbso2 bafang. 750 watt.its a beast as I live in Scotland and there's lots of hills and steep ones too so my e bike is a must.i find the 1000 watt motor here would be too much and the 500 watt would not cut it for me as all the hills in my area.hence y I got the 750.i love it.does 38 miles hour so it brilliant.🙏🔋☮️🤘💯I do limit the speed to 15 miles an hour tho on the roads just Letting all tha Karen's know ye 🤣🤘☮️
Good kit , up and running , how most humans want them..
lol
Change front fork to disc and suspension
Suspension seat, and you got a good custom build
Nice Video! Thanks a lot. But please tell me, where is the controller? is it included in the battery mount or in the motor itself ?
Its inside the motor housing
I heard the throttle lacks power? I like to use the throttle when crossing intersections up hill. Can it give me enough power to get going until I start pedaling on an incline?
I want to remove my Bafang and install the Tongsheng because I would love to have a torque sensor rather than cadence.
The Bafang gives you a gear shift sensor which I think is important. Not sure why the Tongsheng doesn't have that.
Hi,can i use a 48v battery on the TSDZ2 36v 350W kit?
I think so, according to endless sphere
If you are ONLY interested in pedal assist, can you simply miss off the throttle and the brake sensors? Does the torque sensor react quickly enough when you brake to cut the power?
I didn't install the throttle and I also blanked off the cable with self amalgamating tape as I wanted a pedal assist bicycle and it has been fine for the past two years.
I have the same kit on my bike can I add a throttle? It seems like it
İs this 48v 500w kit suitable with 13s 48v battery?
I have a rad city 2017. The regen only activates when I pull a break lever part way. . but the geared motor always causes resistance . . so i have to pull my break to activate it And I can't even coast down hill or flat as the geared motor will slow me to a stop with no breaks. Its a good bike but good grief I love the feel of coasting.
Hi Marcus, it sounds like your RadCity has a gearless direct drive motor (I actually know this to be the case), and yes, they do create some magnetic drag. It's one of the trade-offs for durability and regenerative braking ability. Not much that can be done... their geared hub motors (and most geared motors from other ebike companies) do freewheel more efficiently :)
@@ElectricBikeReview easy to get confused about geared and gearless motors. Sorry for that. Its maybe the rover that has a geared motor I forgot as ive only had it a month or so. And watched way too many videos lol. I cantbelieve that's all magnet I'm feeling wow. . . powerful motor. Climbs hills like a beast. . I test rode a mid drive but at 2400 $ I took the 900$ used city. Its a 20 inch but I grew up on ten speeds I didnt fit. So I can deal with that. I'm only 5'10. I want a fat tire in the future . . . hmmmm. . I got my eye on rover and rip current. . so many brands out there. Electric motor cycles look so awesome but I can't forget I'm OLD and broken so electric bike yes . . . off road on electric motorcycle. . maybe not so much. . . getting old sucks. Love your chanel. Watched a ton of videos before I let price and availability decide for me. . worked out well enough. Thanks sorry so long haha
I just bought this kit, I installed it but I got error 30h when turning the display on. It is a 850c display. What can I do to solve this problem?
Does this engine use the opensource firmware? (As I see it uses an 850C screen instead of the classical VLCD5, VLCD6 and XH18 screens)
See link below in Casainho's comment if you're still interested.
I have a question for expertise: My bike has lots of lights and a small sound system. Can I use a car battery for my ebike?
Most electric bikes operate at 36 or 48v. If you sound system does as well, then you've got your foot in the door! Check out Micah at eBike School, he's got a lot of good information in that regard.
@@BlueMonkeyBicycles ok thanks. One more question. Do you make custom batteries?
@@TIMELESSBACKDROPS Very rarely. Normally I use a production eBike battery.
@@BlueMonkeyBicycles Im trying to get a battery built to fit in my motorcycle gas tank. Any suggestions?
@@TIMELESSBACKDROPS I don't have any, I'm sorry. A battery of that physical size won't propel a vehicle of that weight for very far. You'll likely need to open up parts of the frame to accommodate more space for batteries.
For an EV conversion of that size, it's generally using small EV car parts, rather than eBike parts. You can try Carl at EV drives (www.evdrives.com/) or Justin at Evolve electrics. (evolveelectrics.com/), They can likely get you in the right direction.
Hola, desde España agradeceria saber si alguien sabe ya como delimitarla?
I believe I have the same motor but it doesn't seem to like the 48v battery. It just doesn't do anything. When I install the 36V battery the motor activates and assist with peddling. Do you know why it wouldn't take the 48V battery?
I read on the endless sphere forum that the 36v motor's stock firmware causes the motor to not work with a battery above 40V. The 48V motor firmware does the same but at 50V or 55V. The open source firmware linked to in another comment on this video seems to be able to allow you to use a 48V battery with the 36V motor.
👍🏻👍🏻👍🏻
@21:46 rice rocket over there
Use a battery adaptor bracket from Rockcutbikes.com for mounting the battery properly without drilling the frame.
Very expensive !!
Why to buy this unknown mid drive when there is a bafang motor?
I only see viable 2 reasons for mid drives (and I hate the sound when it yanks hard on the chain, freaks me out that it's gonna snap and shred my leg) over current gen hub drives anymore:
1. Class 1 MTB's that are considered "trail gentle" by people worried that anything over 250w will tear up trails
2. Conversions. My main eBike is a geared hub 750w, and it's my favorite, but I am working on converting an old school banana seat low rider :P
It is not unknown and has torque sensing
price?
Sorry about that! Just added it to the description and full writeup, it's $1k electricbikereview.com/eunorau/48v-500w-tongsheng-mid-motor-kit/
When it works it's good motor. But will break down. Bearings are pretty cheap quality. And they use a wave formed spacer in axle and mine broke causing a lot of play. Blue gear bearing broke after 800 km. Large one way bearing on driveside will wear causing play. And built in PAS sensor ring will brake when parts have play sideways.
All parts can be replaced but not easy job.
yo compre un motor tongsheng y a los pocos dias no funcionaba
3 hours .it shows..the wiring is a complete mess :-} Would be interesting to see a side by side comparison to the Bafang 750.
That's a cool idea Rob, I haven't covered the BBS02 for a while now, maybe Mikey has access to one? Here's the old review I did on it and the BBS01 electricbikereview.com/brand/8fun/
@@ElectricBikeReview I have the BBS02S which I just competed on a Giant XTC conversion ..just trying to figure out some lag issues with the PAS and throttle..seems to be a common problem which the Tongsheng doesn't have. I'm hoping reprogramming will address this. Something to consider is that many MTB's have too small a triangle to fit the Hailong type battery pack..very important to figure this out before ordering the kit from China.
The real mess was getting off the bottom bracket from the donor bike. Wiring was a piece of cake, really.
@@BlueMonkeyBicycles It's worth spending some $$ on a fairly new good quality bike with hydraulics and reliable indexed sifters given how much the battery and the rest of the kit costs. My second build was so much more enjoyable than the first where I basically ended up replacing compnents and also dealing with a very tight bottom bracket ..in the end it probably cost the same..
@@robvannNS Ha ha! I thought the same thing! During the written review I lamented heavily that I used this bike and not something much better.
I'm aiming to do more kit reviews in the future. What bike would you recommend for adaptability to different systems?
Drink every time he saws gusto. Just kidding.
Not a bad video and an interesting kit.
They are looking for dealers of their ebikes and kits
Just tape the battery with electrical tape and charge the battery on the bike in side AND KEEP THE BIKE IN SIDE
Checkout eco-ebike.com
I bought a 48v TSDZ2 mid drive from them. They're the only company that I know of that is tinkering around with this kit. They have an overdrive version and they're programming third party computers for it as well. Their website *sucks* but they are very friendly and helpful if you email or call them.
I plan on converting my wife's Diamondback next using this mid drive. The mid drive feels very similar to the Bosch system on a Haibike. All in all this motor makes for a budget friendly ebike that performs very close to the systems used in the higher end ebikes.
this may be and old bike but some may take it as when tuned up old honda civic smokes new supercars on drag race lol
you know you can add drink bottle mounts , go to RJ the bike guys channel and watch video
That is the exact issue that is going to lead to E-bike regulations, the tires were questionable and people are doing this and insurance companies are paying out for injuries, insurance companies will only pay so long before they start up with their lobbyist and get laws and regulations going. Please make sure your bike is in good shape before you are going down the street with cars at 20+MPH.
Personally, I wouldn't even ride an E-bike that doesn't have disc brakes. Rim brakes might work fine, but I distinctly remember how crappy they are if they get even a little wet, and I'm not trusting them at 20MPH.
there is e bikes with rim breaks in shops made by approved manufactures, if it was unsafe it would not be approved, i been down hill thousands of times at 20 plus in wet, with rim breaks, you slightly use the break to remove the wet before you need them more as you get to the end. but not many ride in the wet. unless caught, and then its get home time.
@@tonyrichardson2637 that’s all fine and good, just know insurance payout = regulations.
ARGGGH ten whole minutes and you are determined to make me comatose. It says review, not installation instructions for amatures who ...
buy a 750w 48v tsdz2 for 296 on ebay. loool 1k? foolish
"Braze-ons"? They are called & referred to as "Brass Bosses" - As well, they can be drilled & installed anytime you'd like... A lot to learn yet mate 'eh?
Everybody calls 'em braze-ons around here. Yes, I know they can be installed anywhere, but I didn't have access to a full bike shop.
Search CZcams for: "rivnut installation without tool". You can drill a hole and install a M5 rivnut anywhere without buying the expensive installation tool that works like a rivet gun.
Just simply painful to listen to this video you could have some of this up in 7 minutes
All I saw was you,, nothing of the kit as you rode
You really need to step it up as time after time its the same old review just a different name on a bike and every bike you review is always the best. This is getting boring so you need to do more rides like your New York City ride and San Francisco City ride. Then review the bikes at the end after the ride.
Talks 98% shows his face 98%, actually showing motor in action 2%.... Shut up and give us actual riding experience with statistic
Very out of date review. There is a newer motor and controls .
Who is this guy? Just go to Lunacycle.com for ready stock of these kits & so much more - you'll be glad u did...
Well that sucked!
