    I like how you ride the bike stock to get a feel for it first 👍 Thanks for that shout out at 3:41!! I wasn't expecting that lol Made my day! Good tip at 7:50 about identifying saboton v1 / v2 controllers!! That's a smart idea at 16:16 to weld the torque arm so it can't pivot!! That's how my Grin Tech torque arm failed, it was able to pivot! I like the build very cool bro and its Big Teedos Bike thats awesome!! Looking forward to the rest of the build! 👍👍

    It's nippy up here in the NE. I added a 1000w dd front to a 500w rear geared ecotric bike I bought 6 years ago. A 60v for the front on a back rack and a 52v frame triangle for the back. Super torque from line and hill climbing. With the 2 batteries , 2 33amp controllers I got great range. 30 to 40 miles. My speed was 35mph flat the bike is super heavy. For the winter I went to a 1000w bafang geared with the 60v battery and 33amp controller and took off the front motor because its to much work to take the battery off since I have the frame enclosed with panels. Cant leave the battery outside below 32F NG for battery. The bike goes 38-40mph flat on the one motor and the front comes off the ground easy. I went to 203 and 180 rotors. Waiting for another 500w geared from ALIexpress to put on the front of the bike for more off the line torque. Its a bit lighter and will use a smaller down tube battery. A torque arm bolted to the caliper mount is best. You need a torque are that will actually hold the wheel on if in the worst case scenario the dropout breaks. For the front I use steel forks. You can find steel spring suspension forks. They put them on the cheap fat tire bikes.

    You are putting a lot of trust in those fork dropouts. I’ve seen several times on endless sphere were the drop outs of the suspension fork Snaped off from hub motors. Typically a solid non-functioning fork made of steel is the only option for front hubs. Even those can break which I’ve seen once and it was only a 350 W geared hub motor. But yeah, super risky putting that heavy hub motor on that cheap suspension fork. Hopefully the owner of that Bike doesn’t try to ride off-road.

      Hi my friend, yeah agreed from what I learned when building my custom ebike these type of front forks are usually said to be good for around 250 watt with one torque arm installed but under greater torque stress from a hub like this 2000 watt the alluminum dropouts have been known to sometimes crack just something to be aware of just keep an eye on them, but if they are straight steel they will just bend not ideal still but slightly safer under more torque from bigger hub motors like this, as for those washers for the rotors maybe you could of dremelled them down slightly to fit in against that recess/taper but you would think they would supply the correct size washers or have an after market all in one spacer to account for this issue! :) @@E-bikeguy​

      ​​​@@tjrcukForks are cheap...ride em til they crack or dont. My stock 2010 Trek 3700 front fork held up one year so far with 1000W hub motor with no signs of stress. I think people dont fit their hubs wheels properly...not running a spacer, too wide hub, etc. THAT will break your dropouts and your suspension fork wont even travel properly making it even more rough on the dropouts. If me dropping 10 feet of kilter onto rocks doesnt break my fork, I cant see some rotation doing it either. Depends on the fork and power level obviously, but in general, MTB forks of any decent quality can handle a lot of abuse.

    I like the fact that you welded the torque arms. 2000 watts is alot of torque on the forks. And the throttles on the same side is unique but if that was me I'd would have on on each side.
    I have checked out BigT's channel and he goes on long rides. Not a fan on those tires but to each his own. I would upgrade the tires , with all that power rolling resistance won't be an issue.

    As soon as I saw AR Kepler I wondered if you were working on Big Ts bike. May I make an engineering suggestion? If possible, move the geared hub to the front and the direct drive to the rear. The reason being when not using the front wheel you don't want it making drag. Unpowered gear hubs don't have drag; while unpowered direct drive motors have some drag as they are trying to make power. (And it's in a better position for regenerative braking).

    • @E-bikeguy
      @E-bikeguy  Před 8 měsíci +1

    • @imho7250
      @imho7250 Před 8 měsíci

      No need to swap the motors front to rear, you can still make the front motor the master motor as it should be. The regen will work fine in front (if the controller supports it. It’s just a matter of setting the controllers up correctly.
      AFAIK, the concept here is adding a front motor kit (normally intended for converting a non-ebike to an ebike), and it will be the main motor. Then, with proper wiring, the rear controller will be activated by a button to assist the front motor during acceleration or hill climbs, then once up to speed the rear controller switched off and allowed to freewheel. Cruise is entirely front motor.

    • @ebikeengineer
      @ebikeengineer Před 8 měsíci

      @@imho7250 You're right in that can work, however using a 2KW front motor brings up some safety issues. I never use more than 750W on a front hub that is the primary drive. To much risk of losing traction on a turn when under high power IMHO.

      ...hmm, yeah I was thinking that - regarding too much power to the front wheel...
      If I was doing it, I'd want the rear wheel to have the most power and the front wheel just free running with a small amount of rolling power just to not hinder the rear wheels efforts and then have the front wheel (on a separate throttle, or if possible on the same throttle with a 60/40 set-up) as an aid for getting up hills easier.
      I'd be worried that if too much power was being supplied to the front wheel that when cornering it would slip out from under me causing a bad accident/fall.

    • @imho7250
      @imho7250 Před 8 měsíci

      @@ebikeengineer , watts is not torque. The rear 1000w motor will have as much torque as the front 2000w motor. And it really depends on the Kt of the motor.
      For example, my ebike originally had a 400w geared motor and 15a peak controller. Top speed 33 kph. Then i replaced it was a 22Kv gearless 2000w motor and with the same 15a controller, torque was only about 50% of original, so Kt was about half.
      Then i installed a spare 30a controller and regained the baseline torque but that was only enough to get you run over from behind. Lol. Then i installed my 72360 Fardriver and higher power battery and now send 50a peak and 100a boost. Even with that there is no sign of loosing traction or doing a wheelie.
      Also a major issue on front motor is the torque arms. Ebike guy changes the terrible design torque arm into something that actually can do its job simply by welding the two pieces together. This somewhat lessens the need to install it behind the forks like should be done with all two-piece torque arms.
      Since the front controller is programmable it can be set to keep torque and ramp up soft enough while still getting the speed.
      There are special C-washers for these types of forks that absolutely must be installed. I cant see in the video if they made it in there. Its the washer that goes in the quick release recess and clamps down on the aluminum dropouts to help keep them from spreading as the axle torque tries to spread them apart.
      Hopefully the torque arm was welded such that it preloads the axle flats and converts the torque into a 50 pound forward push instead of a 500 lb force of the axle trying to spread the aluminum dropouts.
      The tuning of the controller can change the motor from an impact wrench into a smooth torque wrench, and regen can be set mild enough to prevent it from reverse torque on the torque arms. Its often that back and forth than loosens things up enough to move, and thats when things go bad fast. Lol

    I'm just wondering if anyone's actually wired up 2xhub motors to the one controller & battery, you know would it work?
