    Bafang BBS01/02 on a bike with hub gear and footbrakes?

    Hey, I want to build a Bafang BBS01/02 (is there another difference but 250W/750W here?) on a beautiful locally produced bike. It has different options of Shimano hub gears. I have read that pedal assist on crank drive is a bad idea with hub gear. Does anyone know if this is true? If so, is it...

    Standard bike wheel only fastened at one side possible?

    Ok, probably just try with the 20" wheels then.

    Standard bike wheel only fastened at one side possible?

    Thanks for the overwhelming response! Great forum! So, if I have understood correctly, the best thing to do is: - Use 20" Wheels with 14mm axle if I want one side and cheap - 26" could work, probably need a fork (both sides) - Lefty/Monofork, sweetest solution but expensive I think two...

    Standard bike wheel only fastened at one side possible?

    Hello! I'm building a tadpole trike at my Uni's workshop now and I have two identical standard 26" bike wheels. On a regular bike the wheels are fastened at both the left and right side by the fork, but on my trike i want it to only be fastened at one side, like this velocar...

    Friction in hub-motor, is the controller or motor broken?

    Ok, so when I open the controller chassis, is there something I should look for to realize that the FETs are blown? (Must admit that I don't know what a FET is, just saw some pics on google now.) Just burn marks ect.? And if it is blown, is the FETs somethings you could buy separately or are...

    Friction in hub-motor, is the controller or motor broken?

    Thanks for quick answers. Thats good news! I was hoping to keep the motor intact! It is frictionless when not connected to the controller. Is this good or bad news? Are you saying that the problem could be that inside the controller there is a short cut between the three wires? If so is there...

    Friction in hub-motor, is the controller or motor broken?

    Hey, while driving my 1000w 48V ebike (cheap motor/controller from eBay/China) yesterday the engine suddenly stopped working and was no longer frictionless. From the engine there are 3 thick wires and 5 small (see picture) to the controller. The interesting part is that if the yellow wire...

    Would this steering mechanism work on a tadpole?

    Thank for all the great input! I've read about Ackermann, and I'll probably end up with that in the end, just want to consider some ideas first:) Could it work if I used the single rear wheel for steering, and the two front wheels for pedaling? And if this work, would it be possible to have...

    Would this steering mechanism work on a tadpole?

    I'm making a tadpole bike for a school project and I'm wondering if anyone has come across a steering mechanism similar to the drawing I've attached. I see that the "steering pole" can't be to close to the wheel, because then it would hit the tire when turning to the right. Do you think it...

    Uphill, no pedal, 20" 1000W 48V possible?

    Thanks for great answers! I think I'll try the 20" inch wheel without modding the controller first, and if it won't work I'll do that. @ Leffex, I'm building a trike for a project at my university:)

    Uphill, no pedal, 20" 1000W 48V possible?

    Hey! I'm new to this forum and last week I managed to get my 1000W 48V 26" rear hub motor from China to work with a 48V20ah battery and i love it! I goes much faster than I expected also uphill if i help with the pedals. My next project will be to build a trike with no pedals. I understand...
