Re: Dave's 80:1 RC mid drive kit build log

Wow Dave I am impressed.....that is definitely the longest ebike beating I have witnessed. Of course it is easy to criticise riding technique in retrospect, but we all know in the heat of the moment throttle usually equals fast. I bet just smoothing out the corners and carrying more speed would of l...

Re: Dave's 80:1 RC mid drive kit build log

I am very interested in Vedder's ESC. The builds I've seen are good for 12S/50V, right? The 3210 7turn is 195Kv. I wonder how much hassle it would be to increase that voltage handling up to 96V...? Yes 12s capable. Though I do believe a low Kv is required and a few have fried DRV chips (from memory...

Re: Dave's 80:1 RC mid drive kit build log

Hey Dave, have you tried riding the bike with a simple throttle interface instead of the CA? I gather you probably limit the power to keep the derailleur etc happy. If you haven't already seen it, there is a controller being developed in the E Skateboard section of ES called VESC. It is doing good t...

Re: Single HUB motor, VESC Loaded Dervish Build

I replaced the nunchuck dongle with another nyko nunchuck dongle and it works well now... looks like some of these nunchuck receivers are crappy just to confirm did you exchange nyko for nyko or another brand?

If you use the Wii remote that Ben and jacobbloy have been working on, you can press and hold the cruise button after a few kicks and it will maintain that speed.

Re: Dave's 80:1 RC mid drive kit build log

Reducing the overall ratio, I'm thinking the same. An 18t motor freewheel would put us at 70:1, 145 crank RPM. The motor could push each gear 15% farther than the 16t and use the lower gears a touch more. Maybe it's nicer to have the motor outrun the pedals, have more headroom in each gear. That 11...

Re: 20 inch full suspension street build (now with twin moto

ha, I have the same issue with it overshooting randomly, even set for something silly like 30A it will still pull like a train for a split second sometimes. Though mine is a BETA version of the RC-CA, I have fiddled with it endlessly to try and solve it.....but never looked at the ESC settings :lol:...

Re: RC Mid drive project - trial/freeride style

well that blows that theory then.

Try a HV160 just to check that it is not the controller creating the heating. Then I guess you have 2 options, rewind or increase V.

Re: RC Mid drive project - trial/freeride style

That video isn't mine....just a demonstration of the power you should have. You might have more torque per amp but the higher the rpm, the more multiplication is done via reduction.

Did you weigh the stator before and after rewind?

probably around 7000 - 8000 RPM Im pretty sure it might of been thud that experimented with the max rpm of these motors....from memory the efficiency went out the window close to the factory 130kv wind on 12s so 6500rpm, forgive me if I am wrong.

Re: So I bought a lathe...and made Hub Motors

do you mean if you run a normal wheel on your truck that is modified on both sides? I assumed when you made that slip over extension its offset would be the same as original? if that isn't the case what stops you from extending it further or moving the motor out more?
