Re: Rans Stratus - Recumbent

What neptronix recommends there is just about exactly what I did with my old Ryan Vanguard, and it ran pretty well. Except I left the regen configured to the the usual modest force. Then I moved the motor to a Burley Limbo, because the Vanguard is such a fine classic ride on its own, and at the high...

Re: Are footpegs superior if you don't pedal?

My guess for most frames Bicycle frames, that is, am I right? For an electric scooter, the principles behind bicycle ergonomics are somewhat misplaced. For an ideal ride, some kind of moped frame would probably work a whole lot better. Maybe one of those mini-motos that were popular a few years bac...

Re: Leaf / leafmotor / leafbike high efficiency 1500w motor

I'm interested in seeing how this turns out for you. I've found the opposite; increasing regen decreases range because the bike brakes harder and the time regen is active is shorter. Moderate regen seems to pay the most dividends on my bike, but maybe that also has to do with terrain and riding con...

it would've been a potentiometer mounted to the pivot of a springloaded roller on the top side of the chain, and the voltage on the pot would've been detected by an op-amp and amplified and turned into a throttle signal, calibratable with pots on the op-amp...there are better ways to do it but that...

Re: The E Bike Act HR1019

Different way to say the same thing. If you're shopping for an electric bicycle, and I give you, and you only, $1,500 to help buy a nice one, then that's just good for you. If I give everyone $1,500 max, then the prices will go up so you pay the same. This is more reliably true with something like t...

Re: E-ASSIST not throttle rocket!

It's true that if you have a motor, as long as the battery is good, gear shifts are less important, so it will be easier to get along without the Alfine. Until the battery runs down. Personally, I do shift quite a bit, but the point is I don't strictly need to, so if I'm stopped in high gear, that i...

Re: Help with an e-bike for my courier job

I love regen, but I have the most use for it down hill. For quick stops on flat ground, it seems to me you'd have to dial up the regen force pretty high to get much value out of it, and just generally it doesn't seem worth it. Considering the trade off, which is that you'd need some power to the mot...

Re: Seeking advice for commuter e-bike setup

Direct drive, with some cooling, controller with regen and 52V 20Ah battery should do it. Basically you're using power climbing about half the distance each way, so need around 18 total miles worth of assist/battery capacity. Or, you can have a smaller battery and assume recouping a portion of the ...
