Yeah, so far I'm quite pleased with the motor. He can handle so many amps/volt without breaking a sweat :D But the drag is terrible, had to cycle once without battery it was really hard. Not sure yet about efficiency, need a CA for that. I'm looking for an inline fuse holder that could...

Danger has also a huge impact on people not going on bikes. I know many people that are interested in my electric bike but would never ride it because cycling is really dangerous in London. Just had a small car accident because the driver wasn't looking when he turned left. Broke my brompton...

Jstv, what was lock was using your son? I suppose not a gold secure lock?

Frank, the Kryptonite Faghetaboutit has been tested with other locks and has the highest security score: Locks that work - London Fixed-gear and Single-speed On the test, they took 3 mn to cut through it and needed 2 discs to do that. (1 was killed in the process) Shouldn't that be strong enough?

Thanks for your answer. I'm not planning to lock it overnight but sometime I go out and I need to park the bike outside for few hours. So maybe a kryptonite D-lock on the frame + a cable lock to secure the wheels should be enough? The Fahgettaboudit mini lock seems to have good review...

Ok thanks Jerry, I've read 290$ for the motor only. Going to ask them directly if the motor can go a little bit faster.

Jerry, how much did you pay for the motor? If the controller is not build in, maybe I can aim for 20mph with some overvoltage? Thinking of maybe getting a lightweight version of my bike :)

I'm thinking about locking my brompton outside. Need something quite strong but not too heavy at the same time. What about just using the Kryptonite U-lock? Kryptonite New York M18 Lock | Evans Cycles Or shall I go for a super heavy 5.5 kg chain lock? Kryptonite New York...

This is a 45 amps controller at 74V. So probably around 3000W lol Not sure however, the CA is not compatible I have to find a way to measure the current and speed to have my idea clear. Not sure either if I'm at 25-30 mph as it look much faster on small wheel. Will tell everyone as soon as I know

I'm trying to have regen with my controller: I'm however not sure how that works. Any idea which cable I should plug for that?

This one is a 9 pins cable for motor: A pair of 9Pin Waterproof Male/Female Connector Cable for Motor - BMSBATTERY

Thanks. Just purchased them with the 25 pins DB connectors. Will see what they worth :)

Guys, I may have found my connectors: 5x pairs MPX connector plug 24K gold 6-pin 40A RC LiPo | eBay Really small, and able to handle 40amps. There is a good area to glue them together, maybe I can even have only 1 plug!

Yeah I agree with you. The problem is that I'll use the motor on a 16 inch wheel. So at 260RPM it's around 12-13 mph. And I can't really overvolt it as the controller is inside the motor and will be limited to 36V...

Yes, I'm planning to have another connector for the phase and the batteries plugs. Something such as a 5 pins 45A connector. But I have a lot of connections for the controller: - Cycle analyst direct plug : 6 pins - Brake: 4 pins - Hall sensors: 5 pins - Throttle: 3 pins - Regen: (don't know...

Thanks John, without your help I wouldn't be able to complete this project. :) Now it's time to make the bike work better. :)

Thanks Laroche. I'm also thinking about a lightweight bike. But damn 12 mph would kill me.. Too bad it's so restricted.

I'm thinking about moving all my connectors from my controller to an unique connector: D-SUB 37 Pin Female Solder DB37 Type Connector x 10 Pcs | eBay Could work for everything except for the batteries. So I'd have this multiplug connector + batteries/phase wires connectors together. Would that...

Thanks for the feedback Laroche. So no controller needed? It's integrated with the motor? I'm wondering if there is any way to increase the RPM? I suppose at 260RPM on 16" wheel, the bike would be really slow (around 10 mph)

Thanks for this explaination Flecc. So for hills and stop&go we have: - Crank drive > Geared motor > Direct drive motors And for the opposite, just straight road we have: - Direct drive > Geared motor > crank drive Still not completely convinced by crank drive, if there is any issue on the...
