    2 speed (could be auto) gearbox

    Did anything ever come of this? I've been obsessing about 2 speed gearboxes lately and remember this concept from years ago. I recall there was another member that did this as well but I can't seem to find the thread.

    Asynchronous motors - is induction the new future?

    I have yet to read through this whole thread, but I'm so excited after just discovering this that I have to post now! I have been dreaming of an induction hub motor since I got into ebikes and have spent many hours contemplating on whether such a device would work as a hub motor or outrunner...

    What is your reason of building ebike?

    Biking is one of my favorite activities. Getting out into nature alone and exploring. The ebike will allow me to go out past my 15 mi radius comfort zone. Also the second reason is that I'd eventually like a fast ebike that could compare to a low powered motorcycle/dirtbike. When I was younger...

    Best rear suspension system for a rear hub motor?

    I would think the good ol single pivot would be best, just like a motorcycle uses. I could be wrong but I thought all those other designs were made just to take down pedal bob

    Why can't you run 2 brushless motors off 1 controller?

    Ok I was actually theorizing a dual motor offroad rig and would want both motors to stay locked at the same rpm. This could be useful when going through slippery or loose terrain and trying to maintain speed when 1 of the wheels loses traction. I thought they would work in a similar fashion to...

    Why can't you run 2 brushless motors off 1 controller?

    I just can't seem to wrap my head around this concept. What would happen if you took 2 hub motors and hooked the phases up to each other and then spun one of the wheels? Would both wheels spin at synchronous speeds? 1 acting as a gen and the other as a motor

    Full Suspension XC vs Downhill Frame For Light Duty Offroad

    So I wound up buying a Jamis Dakar XCR. It's an 07 model, with deore LX shifters, hydraulic brakes, upgraded rockshox RL3 air shock and a 100mm air fork. Only weighs 31lbs Nicest bike I've ever owned! I bought the bike because it had full suspension and because I thought the frame had a lot of...

    My firts ebike --- MAC, Bafang, MXUS???

    I completed my first build not long ago and used a 2808 9C motor and have been very happy with it. Lots of power and fairly low cost compared to some of the geared motors.

    Upgraded to a FS frame, downgraded performance.

    Just an idea, maybe heavier weight oil would give you better damping?

    Full Suspension XC vs Downhill Frame For Light Duty Offroad

    Yes I would like for the majority of the weight would be inside the main triangle. As I mentioned I'm using SubC cells which means they are very small and versatile and I can pretty much solder them into any shape I want. Of course this makes the project much more complicated, especially since I...

    Full Suspension XC vs Downhill Frame For Light Duty Offroad

    I had the batteries donated to me and I have about 800 of them. They are pretty high quality cells as far as NiMH goes. 5000mah subC tenergy propel cells that can handle 30A continuous discharge. 3 strings at 72v would give me my 1080Whrs. I have 20lbs of nimh on a rear rack on my current build...

    Full Suspension XC vs Downhill Frame For Light Duty Offroad

    So I know alot of you guys go for the DH/Freeride bikes for high speed and serious offroad machines. I'm looking at a Giant NRS XL Frame that I can get a good deal on. How well would something like this work for moderate offroading? Dirt and grass trails with the occasional log and rock I...
