Re: Electric handbike

I think the Q100 is a bit small for operation by the throttle alone. It'll work, but I think the Q128C will be able to handle the torque much better. The Bafang CST would also be good, but I'd get the 500w version if you can because it's the same size and weight as the 350w one, but it can handle a...

Re: Electric handbike

I think you're right and that option 1 is indeed the best. Although I personally would still get a 48V battery with that motor. Then even with voltage sag and going uphill you can still reach 25km/h and above. And you don't have to go faster than you like but you can if the road and circumstances a...

Re: Electric handbike

Ok, he decided to go with Q128C motor. So we have two options: 1. Q128C 48V 328rpm version powered with 36V battery....that should give 260rpm (perfect for us). Is this correct? Powering 48V Q128C with 36V battery will cut rpms to 260 and lower torque? Will this affect the motor in any other way? 2....

Re: Electric handbike

Ok i spent a weekend reading hundreds of posts on the forum...really impressive amount of knowledge here. I think two guys posted about 201rpm Q128C being actual 260rpm, d8veh and one other guy... Few guys posted their setups that could be calculated back to 201 rpm... BMSB do not know what i am tal...

Re: Electric handbike

...found it... Just to add a bit to the above, the 201 rpm Q100s and Q128H are actually around 201 rpm but the 201 rpm Q128C is 260 rpm - or at least it has been for all those that have bought one so far. On the road speeds with a 26"wheel are: 201 rpm = 15 mph (19mph with a Q128H and fully charged ...

Re: Electric handbike

If he needs to be able to use the handbike manually without motor assist then you should choose the Q128 geared hub motor. The Q128H is the version for a freewheel gearset and the Q128C for a cassette. Yes, Q128C is my favourite too. But it only comes in 201rpm and 328rpm. Sweet spot for our setup ...

Re: Electric handbike

Thanks for your idea SlowCo, u got me thinking now... Ok, big and heavy motor is strong and fast enough (maybe too strong and too fast for our needs), we can use regenerative braking (which is great safetywise), it adds weight to the front wheel (which is always needed with handbike) and with progra...

Re: Electric handbike

How would you operate a throttle? He is quadriplegic so he has very limited hand control and nearly no finger control. He can not push thumb throttle with his finger so he kinda pushes thumb throttle with his hand (thumb throttle is on a special lever). He operates brake and gear shifter the same w...

Re: Electric handbike

If he isn't tackling big hills I think the Q100h would be a good choice. Get the sine wave controller to go with it and you will be amazed at how smooth and quiet it is. Contact BMSB about compatibility and specify that you want throttle control. Their shipping is sky high so think about what spare...

Re: Wheelchair e-wheel atachment

OK let`s assume it is Q85... Q85 comes in two speeds 201 and 328. Probably they use faster one because of it`s size. So if i overvolt 36V Q85 328rpm with 48V 10Ah battery i should get over 430rpm or around 25kmph in 12 inch wheel....that is very similar to overvolted Q100H in 14inch wheel... Is that...

Re: Wheelchair e-wheel atachment

Thank you for the link @SlowCo... After reading @spdas thread i think i will go with Q100H motor and overvolting it with 48V baterry and 18A controller... that gives out: - 20 kmph at 350 rpm in 12" wheel, range 76km - 23 kmph at 350 rpm in 14" wheel, range 67km Motor simulation comparison: 48V Q100...
