    Motobecane Phantom DS with Cyclone 900w

    This is a Motobecane Phantom Elite DS bike with a 900w Cyclone 3-chainring kit. I've managed to slap everything together so that I can blast around at 35mph but there are still some bugs to be worked out. I've got to find a decent spot to mount a controller, and I will probably be replacing...

    Need some help with disassembling a 900w cyclone motor

    I've got a loose wire coming out of my 900w cyclone motor. Unfortunately, this loose wire appears to be the one that contains many other smaller wires. I can see a few silver strands sticking out that are loose. I'm assuming these wires are for the hall sensors and the other 3 thick wires are...

    Wanna see some typical ebike controllers?

    I thought I'd share my small collection of brushless controllers for the family. From left to right, listed as what kit or who it came from: 1) Pegasus Power Systems 36v 22a??? I'm not sure on the exact current, but I can only guess its a 22A 2) E-crazyman 24v/18A 3) Lyen 24-72v/30A 4)...

    *video* New GM mini rear hub is wobbling! Is this normal?

    Just got this Golden Motor mini rear hub this week. It seems to wobble like its got a bent axle or crooked bearrings. It doesn't sound like its running smoothly either...it lopes. Here's a video with the GM mini using an ecrazyman 24V/18A controller. It wobbles and sounds the same with or...

    So you want 7 gears on your rear hub motor?

    Ok, so I just received a GM mini rear hub and test fitted a standard 6spd junk shimano freewheel similar to the freebie ones you get with rear hub motors. I was bummed because it barely left enough room for the chain, and I was hoping that magically I'd be able to fit a 7 speed on this hub...

    Anyone using a circuit breaker?

    I'm thinking about trying this 30A circuit breaker from tncscooters.com. Should the fuse rating match the controller's continuous rating, or peak rating? http://tncscooters.com/product.php?sku=101262 Anyone using one yet? How reliable are they?

    Are there any mini hubs that will take 7 spd in 135mm?

    Since I wasn't able to get the "cute" motors, I'm now leaning towards a BMC motor. Especially because they will take a 7spd freewheel and weigh less than a standard hub motor. Before I start pricing the BMC's, are there any mini hubs that will take a 7spd freewheel in 135mm dropouts? Seems...

    Anyone using a different controller with their cyclone kit?

    I recently mounted my 900w cyclone in place of the 360w I have been using on my 20" clown bike. With the 360w it takes about 1/5th of a mile to reach 20mph (full throttle, no pedaling, shifting through all my gears). I'd call the acceleration "brisk" when you're riding on flat, open roads...

    Where to get diodes?

    I'm currently using 100v/100a diodes from Ping, which seem to work fine as far as I know, but would like to find another solution that is more compact. Ping's boxed diodes each measure 7/8"x 1-5/8"x2-7/8", and take up a lot of bag space when using 3-4 of them. They were $8 each if that...

    heat shrink film, where to buy?

    I need to put my PIng battery back together. I should of ordered some from him when I got my replacement BMS, but its too late now. Where do you guys get your heat shrink film? What size and specs should I look for? Do I need a heat gun or will a 1500w hair dryer do the trick?

    Anyone ever broken a brake lever?

    I've already seen the thread about how to use reed switches to use any brake levers you want. Just curious if anyone has ever broken a standard ebike brake lever during hard braking. I'm talking about the ebike brake levers that cut off power to the motor. IMHO they aren't made very rugged...

    Dewalt battery pack case - internal dimensions?

    For those who have empty dewalt battery packs, can someone give me the internal dimensions of the battery casing for 28v and 36v packs? I am wondering if LifePo4 prismatic cells would fit inside the case. I wouldn't try to squeeze the same voltage in there, but it would be nice if 4s prismatic...

    Cyclone 1 chainring owners - checked under mounts lately?

    Hi all, this was going to be specifically directed to 1 chainring owners, but this probably applies to the 3 chainring kits also. If you haven't removed your cyclone motor brackets since they were originally installed x-miles ago, I encourage you to do so just to make sure your frame isn't...

    Ping battery repair - I think my BMS is bad (now with pics)

    I have a Ping 12v/15ah v2.5 that I use as a booster pack to go from 24v to 36v when the need arises. I didn't have any issues with this pack for several months but now I think there is a problem with the BMS. I charged it up as usual, which means until all 4 leds are solid on the pack, and...

    Any throttles compatible with rapidfire or trigger shifters?

    Are there any throttles that are compatible with rapidfire or trigger shifters? To clarify, most throttles have LEDs or a power button/switch to the left of the throttle (larger diameter end with the electronics in it) which prevents you from using trigger shifters for your rear gears. The...

    Cyclone - reverse rotation - freewheel sprocket?

    I'd like to reverse the rotation on my Cyclone motor (1 chainwheel kit) to improve my mounting options. I understand that this can be accomplished by rewiring the connection between the motor and controller. I think the only thing that will be an issue is the motor's freewheel sprocket. My...

    Where to order spokes - 13/14 single butted

    I want to change the spokes out because they will not hold their tension. The nipples were already bent when I received this wheel new. It was supposedly dished before I picked it up, but now that I have the tools to check it, I can clearly see that its not physically possible to dish this...

    Need some help with internal geared hubs

    Hi guys, I'm thinking about getting an internal geared hub but my main concern is reliability and performance. I have a new Dahon Boardwalk S1 that I've modified for a 7 speed freewheel and a cyclone 900w motor. I was considering a Sturmey Archer 8 speed so that I could also get a drum brake...
