Re: hobbyking lipo battery build suggestion

Thanks for the reply! I will do more research on the charger and connectors for balancing the cells during recharging.

hobbyking lipo battery build suggestion

I plan to build a 44.4V 30Ah lipo battery pack using the hobbyking lipo. I have a couple of questions: 1) Is it worth it to pay for the nano-tech lipo? They advertised as having lower internal resistance, hence more flat curve and probably will help extend range a slight bit. 2) What connectors do y...

Re: fastest hub motor + controller combo available today?

It looks like I would need an outrunner motor and mount to hit > 60mph safely without killing the motor. Now my follow up question would be how more efficient are the out runner motors compared to the hub motors assuming both are propeling the bike at 45mph?

Re: fastest hub motor + controller combo available today?

All the motor you listed are motorcycle hub motor. I was thinking of something more in line with a bike. But thanks for the recommendation.

fastest hub motor + controller combo available today?

Hi all, I just finished building an ebike, but now looking to build a fast recumbent trike. I am wondering what is the fastest hub motor + controller combo possible? I seen on youtube some guy got 66mph on his bike using 100V or so. Is there any other people out there that gotten their bike to go ov...

Custom E-bike BMC V3 1000W on GT Transeo Cross-tour bike

This will be a long review, so bear with me. here are the criteria for my ebike build: 1) Hydraulic disc brakes - I wanted to can stop well enough during an emergency. Moreover, the feel of a hydraulic disc brakes is much better than mechanical disc or V-brakes. 2) Hybrid Bike - I wanted a Hybrid bi...

Re: How to Solar Charge an Electric Bicycle

I think for this to be even feasible, you will need serious solar panels and some good sunlight throughout the day. Here is my quick math: My battery: 48V30Ah ~ 1440WattsHours ~ 1.5KWh battery (50 miles range all electric/no pedal) Accounting for inefficiency on energy conversion of the charger I'll...

BMC V3 Motor vibration/noise at 25mph?

Hey guys. I am hoping someone can confirm or at least tell me if there is something wrong with my motor. Apparently, I am getting this loud vibration/buzzing noise when I hit 25mph on my BMC V3 motor. I notice it goes away when I let go of the throttle at that speed or if I hold the throttle and let...

Re: Specialized Enduro Comp / BMC Build Thread

how is the weight distribution? How hard is it to turn? I have mine just finished with the battery in the center (triangle area). How do you lock up your bike? In one of the picture it looks like you have a cable lock. Looks like a clean build. Any idea on Top speed and range on those battery you go...

Re: ElectricRider Phoenix Cruiser II

I am interested in the kind of range you get. Also if you find a way to calibrate the speed, that would be great! I got a BMC V3 motor and I can get 33mph on flat no pedal using 36V at 33Amp current limit and the speedometer is calibrated accurately to a gps. I hear that the Cruiser II can hit 40+mp...

Re: Ryobi One+ Electric Bike Build

Actually it really helps if you put it in the center (in the triangle area). I use to have my battery on my rear rack and it pretty unstable during the cornering. Since the triangle area is lower to the ground, you don't have to fit too much momentum during the cornering to bring the bike upright ag...
