    hidden wire brake sensor... ?

    Looked but didn't see one here. Purchased this sensor for my back brake not the front as I feather them more. The great thing is I can now use my gear shifter brake combo now that came on my original bike. Couldn't figure out how to paste the ad on here.. Item #281294629865 on ebay. Easy to...

    Entry level bike going too fast

    That's well said, when I had my CRF 450, if I didn't drop it, I didn't feel I rode hard enough. I wasn't back flipping crazy but on those trails :twisted: ...moto cross wasn't as forgiving, so kinda stopped with that. But was still looking for the jumps on the trails, lol

    Got me a cheap bike computer

    The speed view app on my phone seems pretty accurate, tried it in 3 vehicles to verify. That what I used till my cheap odometer arrived from China. Under $3.00 with free shipping, packaging and ebay fees...just shows you how much things are marked up here in the usa.

    Entry level bike going too fast

    That's too fast on a bike. Seen and heard that a number of times. It's not ...till you crash. :D My project bike is a Gravity FSX. IMO is a sharp looking bike but considered an entry level bike and a step up from alot of department store bikes. The bike feels solid but probably not as much...

    My ebike is too torquey, how do i settle it down a bit?

    Hobbyking Shipping Issues

    That the problems I had. The product arrived correct but 2 times I was double billed and another time they couldn't find my order but had no problem keeping my money that I sent. Who knows it could be my computer, paypal too. So I guess I really can't point all my fingers. And another time they...

    bike wash

    I know its a mountain bike but I told myself I wasn't going to ride in mud and I accidentally drove through a bunch that looked like dry land... because I was going 85mph. I'm thinking about taking off the motor and controller and pressure washing the rest. Don't want to take a chance of...

    New sunwin controller wiring with KFF pics

    Anyone have this controller and know if it's possible to reset it? Now with the self study cable plugged in it goes full speed forward or reverse, whatever it decides. But does not respond to my throttle. With the on off button on or off, it goes full speed and only way to stop it is unplug...

    new ebike

    The 3rd controller you listed, the 48,60,72v. 1500w I just got one. Shipping was not bad for being so far away, think it was 1 1/2 weeks from China. I think I counted 18 mes FET's inside it. Still trying to find the time to get the right wiring combo for it tho as my motor wasnt just plug and...

    New sunwin controller wiring with KFF pics

    Now I'm trying to use pliers....turned down the voltage... not that 48v cant damage but better than the 72v switch I had it on. Funny how im thinking about that after :idea: So it looks like I need to stick with the throttle cables and not the speed cables. Looked at the 4 downloads the seller...

    Cro Motor v2 Dropout Dimensions with 8/9 freewheel

    Tried the 3 speed one on ebay for $10 free ship. The smallest gear is 16 tooth tho, I cant pedal fast enough going top end,the next 2 bigger gears are nice if the bike breaks down or slower riding. Im looking for maybe a 10 or 11 single gear since I cant find it in a 3 speed. With the 10 or...

    Way to test run a hub motor without the controller?

    Way to test run a hub motor without the controller?

    I was hoping someone say it don't make sense. Test drove it and at 44.4v nominal the bike runs fine. ? Little slow for me but it works and will continue testing it before we spend any more. Must have tried it over a dozen times but the motor or controller don't seem to take the 59v. I hear a...

    New unused motor binding

    Thanks, got it going for now. Tried 14.8v less and the control box took it. Closer to 48 volts. 18 fets 80 volt caps we figure we give it a shot but the controller or throttle rejected the extra 4s battery.

    Way to test run a hub motor without the controller?

    I figured it out...I have a moving wheel! In a previous post we where trying to figure out what size controller I had. It was determined to be 48v controller but with a higher FET than normal. 18 of them with 80v caps. We figured it be ok to run 67.2 hot off the charger or 14.8v nominal. Got my...
