Re: Old Bridgestone MTB Electric Conversion

Wow, it's been a while since I posted here! Happy to update that the bike is up and running. Thanks for everyone's suggestions. The Lipos and myself have been getting along fine. I have several questions on lipos that I will get together for the experts here. So, after completing this bike I am VER...

Re: Greentime controllers

I am running the yescomusa motor with the Greentime 15fet 4410 controller, had to swap the yellow and green hall sensor coming from the controller but is working great in sensored mode, silky smooth but at full throttle holy shit its like hitting warp speed. Even a tiny bit of throttle will hit 20mp...

Re: Help choosing a kit for 36mph+

A 1000w kit can do 30mph crusing, but can burst pass 40mph+ as well. My motor is rated for 1000w and can cruise at 30mph for 10miles at 20amps easily, but I can burst past 40mph for a few minutes but the motor will heat up rapidly.

Re: Just got my ebike kit from yescomusa what battery?

If you're going to ride over 30mph, get out of the bike lane and into the street or you're going to become a statistic when someone doors you. And while I run stop signs under 10mph, running them at over 20mph is just stupid. Don't give ebikes a bad name and you'll live longer. Nice build though. G...

Re: Getting an ebike

I also have the yescomusa kit, and had the calibike 48v 15AH lithium I was topping out at 30mph, but only that battery is only good for 30amps max. Good commuter battery but if you want high performance lipos are the way to go. With 15s and 45A I'm pushing over 2500w.

Re: Max volts for this controler

I have the same kit, I charge to 4.19v, thats 20.97v per pack. The stock controller has 63v caps. https://scontent-b.xx.fbcdn.net/hphotos-prn2/t1.0-9/q71/s720x720/1557722_10201694968072058_2063676546_n.jpg https://fbcdn-sphotos-h-a.akamaihd.net/hphotos-ak-prn1/t1.0-9/s526x296/1962641_102016853053504...

Re: Just got my ebike kit from yescomusa what battery?

Still on the original controller for now, but I beefed up the traces and added more solder to the shunt. Still on 15s, it would be easy to go to 20s but my controller can't handle it (63v caps) Can I just replace the 63v caps with 100v and run 20s? https://scontent-a.xx.fbcdn.net/hphotos-prn2/t1.0-9...

Re: Just got my ebike kit from yescomusa what battery?

I'm having a hard time going past 40A, even though I added more solder to the shunt. Would have hit 35mph if I had more air in the tires. https://scontent-a-sjc.xx.fbcdn.net/hphotos-frc1/t1.0-9/s350x350/1975207_10201626865609539_1241464620_n.jpg https://fbcdn-sphotos-f-a.akamaihd.net/hphotos-ak-frc1...

Re: Just got my ebike kit from yescomusa what battery?

15s1p will get me maybe 7 miles if I pedal and take it slow. But since I'm racing cars and smoking them at the light, and going 35mph I get about 4-5miles. Its just temporary until I get another 15s pack so 15s2p, then eventually 20s2p

Re: Just got my ebike kit from yescomusa what battery?

Went to 15s, 63v wow what a beast compared to 48v. Top speed increased from 29-30 to 33-34mph, the greatest difference is the acceleration is just phenominal, torque has increased. Slight wheelies in going from a stop, and can hit 20mph in a only a few seconds, ramping up to 28mph quickly. Where as ...

Efficiency and Voltage Sag

Are direct drives motor more efficient at 15mph, 20mph or 25mph? Because I seem to be getting better efficiency going at 25mph than 18mph. Also I think my battery is sagging after a WOT burst my battery meter would drop to two bars, after I left off and slow down it goes back to 3 bars.

Since my ebike is using a LED display, and wont operate unless the display is on, can I just bypass it by connecting the red wire to the display and connect it to the controller power wire?

Re: Just got my ebike kit from yescomusa what battery?

I didn't buy the lipo's yet, I'm thinking what is the most cost effective way to buy 4s packs or 5s, I want to run 20s.
What about buying these? http://www.hobbyking.com/hobbyking/stor ... ouse_.html
They seem like good value.
