- In this video we built a 2WD EBike using a Decathlon ST100 Frame and our 2WD Kit from www.AffordableEBikes.ca
What do you think of 2WD EBikes? Is it overkill? Should we have gone bigger? We'd love to hear your thoughts!

Finally installed, coupled with their 52V high discharge. What a sunrise of a ride. On a 2002 Norco VPS DH. Eats hills like pigeons do bread crumbs. Didnt install cadence sensor or brake cut offs yet. Marzo bomber 300mm front forks with dual torque arms installed, just had to file the drop outs a millimeter or so to fit wheel. just as they say, 45/50km/hr up hill no effort. Once more, a great product that needs no alteration out the box. wonder if they worked on new features (one wheel drive possibilities, rear light ...) for the next gen controller? Anyhoot, Fantastic product, easy install and loads of fun... Wow. Really surprising at how fast it gets up to speed.
Amazing! Thank you so much for the feedback!!
I Ordered the kit. comes with motors laced with visibly extra strong spokes (seems well over 2mm), Top quality extra strong double walled rims. Ordered several times from them, BBSHD motor and battery. Always well packaged and delivery in a few days. These guys are for real. Prices are the best hands down. (?7 speed shimano hyperglide???)
Hyperglide on the way! Sorry we had to back order it, you'll get tracking in a few hours :)
Thank you so much for the order ! Can't wait to hear how you like it 😀😀😀
NOOOO dont send yet, We had some correspondence regarding extension backpack power cords and other stuff, plus I want to order another stand alone 2WD controller with slight mods that perhaps you guys can do for me. so dont send it yet till we confirm other items I need from AEB, give me till monday or tuesday to confirm next order so you can ship all at the same time. if possible., Thanks in advance... Have a great weekend guys...@@ElectricBikeLaboratory
Just saw this now, sorry about that!
no need for "sorrow". I just need a while to get my "ducks" lined up to proceed with my plans (time management issues). weird work schedule, holidays , enjoying, and winterising /upkeeping the daily rides Ive already made etc ... first weeks of new year should give me the time/room to go full throttle, which brings to mind a "side thumb type" throttle i saw on your site a while back that should be on my list of items.... anyhoot, soon soon soon... good holidays to you guys. @@ElectricBikeLaboratory
i did that 12 years ago. 2x chrystalite 2kw motor rear and 2kw front with 21S custom pack. modded the 72V 50A controllers to 100A each, putting around 8kw peak in each motor. went far beyond 100km/h and scary acceleration with the front wheel spinning every red light. good times... 😅 until the front fork torque arms snapped
Haha that must have been a beast !!!!
Thats a quality kit
Awesome!
Thank you very much! :)
Great video !! I built a similar bike in 2017 its now done 26000 kilometers. I basically installed two conversion kits onto a decent frame. 2x 36v 250watt motors top speed 48kmph.
That's pretty amazing considering 2017 is a long time ago in the EBike world. And 26,000 km is a whole lot! Very cool I would love to see the bike if you have pictures!
Was it a geared motor or direct drive? What battery did you use and what mileage did you get?
There are two motor bikes for sale that have selector switches. Ive seen a few reviews on youtube. I dont know more than that.
I've seen those as well and really want to figure out if it's doable on these KT controllers because it would be a big deal if so
Great videos as always guys. What do you think of doing a front hub (maybe 500w?) with a Bafang BBS02 or BBSHD setup so you kind of get the both of best worlds? Use the front hub to assist if you're losing traction up a steep hill and to have a backup in case say if the chain were to break? Think it would be beneficial or just a weight hindrance?
It's one of those things where I think if you were doing something like a cross country trip and being stranded with a broken chain is not an option, it would be a godsend, but on the other side of the coin if you're always an hour worst case scenario away from home and only do short rides it would probably feel like a lot of weight and complexity added. I think the acceleration argument is different through, its always fun being able to get up to near traffic speed especially for commuting, and having the extra power can help with top speed.
At least those are my two cents! Would love to hear your thoughts!
@@ElectricBikeLaboratory as far as having the extra traction capability, say on snow I am just wondering if it would be worth the benefit.
All my rides are on singletrack, no street or commuting stuff. Only trails. When trying to make it up a steep climb and the BBSHD is spinning the rear tire, could hit the throttle for the front hub and gain traction.
The only time I've seen someone with this setup, it was just for street/gravel riding so kind of defeats the purpose given the extra complexity.
The Mack Daddy setup would be a Christini awd bike with a mid drive but they're expensive lol.
I was wondering if programming from the factory could set a regen cutoff where it wont work until a lower voltage is seen, say 46v and then cuts off at the upper limit of the battery. Possible?
Unfortunately I don't believe so, the only regen parameter is C13 and allows for selection 0-5 for regen intensity, other than this I don't believe there are any parameters that control the regen
on your site you request a rim size of choice, 20" 24" 26" 27" & 29"/700c. they come pre laced? is that correct?
Hey there yes they do come pre-laced
Amazing video. I'm making a dual motor setup with two slightly different geared hub motors. Will they "fight" each other if the rpm of each one isn't exactly the same? I feel like they won't but that's what some people say.
Hey there , only once you max out the ones top speed , it will become a drag to the other. I believe it's due to a higher voltage being required to power the slower motor beyond it's set point, if it doesn't have that voltage from the battery it still produces this voltage when spinning and it will essentially be doing regenerative braking

@ElectricBikeLaboratory even if they are both geared hub motors with clutches that make it so regen is impossible? They only produce power in one direction.
How did it go ? Did you find out ? Do they fight each other ?
@ElectricBikeLaboratory I actually had to wait forever just to get the motor, only to find out a 26x4 inch tire uses a smaller wheel than 26x4 (duh) so I have to relace the motor into the old front wheel. Only top of that I'm still waiting for the front fork. I do now have the meelod xt600dm and want to put about 35amps to each motor. Besides the flipsky, are there any ebike controllers that run this amperage to two motors?
@@ElectricBikeLaboratory also forgot to ask... how were your tests so far?
What's the highest cage of spoke that you can put in your pack wheel on your hub motor motor.
12 gauge for bicycle wheels 10 gauge for motorcycle wheels
Foc or sine wave?
These ones are Sine Wave, not FOC . Would be cool to see some of these controller companies come out with a reasonably priced, LCD / Pedal Assist Capable Controllers with FOC control. ASI and Flipsky are two with FOC but ASI for a dual controller setup is definitely not cheap and then the Flipsky are not easily integratable with Pedal Assist and Display (as far as I know)
If you have any feedback about potential options though I am definitely all ears! Thanks for the comment!
You're overselling the power output.
These are geared motors.
You can't throw gobs of power at them without seriously affecting longevity.
Your motors are saved by two factors:
You will rarely see peak wattage, and only briefly when dictated by speed and terrain.
It's not like there is a magic unlock or anything user controllable.
That's a good thing, as a controller with such a low power rating 12a continuous, will burn out just using full throttle for any length of time.
If you want 1000w per motor, you need to get it the legitimate way - use motors rated for that power level, and controllers to match, or use direct drive motors where you can run higher than rated power levels, and which can be modified for better heat shedding.
I'm guessing you were trying to hit a price point and hence the 500w motors
A better choice of motor would be the Truckrun FW29/RW29, which are actually rated for 1500w each, and are only like $160 ea with a minimal weight difference. (Landed price would be somewhat higher due to shipping, but if you're buying in bulk, you can get the shopping down a lot.)
I don't know if KT make a higher power dual motor controller, but you could use 2 fardriver controllers for about $170, which are programmable and have enough headroom that you can push a combined 3000w as long as your battery lasts with no danger of overheating.
Yes, the components are a bit more expensive than what you're sourcing but you would get more bang for buck.
Cheaper is not always better, and cheapest never is.
