I use cyclone Kits my best is the 36v 100w for the mountain we live on, but most i make up are 500w 24v & use the 3 chainwheel kit but make up my own crank using cyclone crank that fits the freewheel,their's the chain gets stuck in between -----The -Only battery is LiFePo4 buy the cells & Bms easy (from BMS china-you'll jhave to google it )to make up but make my own pack that will fit any mountain bike(stuffed a whole BMS once though), My next experiment is nu-vinci hub wish to here more on these with 500w or more motors.

I can't give a picture not pc literate enough, but i think it essential that one trys to have the battery forward not back makes better ballance, then load up pannies with goods at the back.
That was a 36v 1000w a real goer, its the best.
I finished putting my ebike electronics in a new box: (click to enlarge)
For those into detail, yep, the front wheel is missing two spokes. I took them off to replace spokes that broke on the rear wheel. The rear wheel lost a few spokes due to a incident a long time back when my derailleur sent the chain behind the freewheel. (this had occurred long before I converted the bike to electric) The wheel's been kinda funky ever since. But I got a pack of 10 spokes coming in the mail and that will be enough to replace all the damaged spokes + restore the missing spokes in the front wheel. So it won't be like this for very long.
Close ups of how my battery box is wired: (yeah it's a bit cramped in there. I may at some point completely re-wire it since there's more wire in there then what's actually needed)
The battery being used is a 36v 12ah LifePo4 battery. Much lighter then the SLAs I used to have. Not shown very well in the photos, but there is 4 retaining brackets installed into the box that hold the battery in place, so it can't move around while I ride the bike. The battery is a tight enough fit so that when the battery box's lid is closed, the battery can't move up/down either, so it's secured well enough that I didn't have to strap it down like with the old battery box. There is a small piece of foam padding on the bottom that the battery sits on top of so that it's cushioned against a bumpy ride.
Eventually it won't be needed anymore since I will eventually put this all on my mountain bike. That bike has front and rear suspension and the padding won't be needed anymore.
It's a 36v 350 watt mid-drive system. Though I will need to upgrade my rear freewheel since there is too much of a difference between first and second gear and the motor doesn't like to run on second gear. :P
Now that I finally got the new box finished, I will soon migrate the whole system to my mountain bike. That bike has front and rear suspension and that's the one I've been wanting to put this on for awhile now. But the battery box I had before was too large. I need to get smaller tires though since the 26x1.75 tires are obstructed by the motor (yes I tried installing the motor onto that bike and would have to tilt the wheel to the left to avoid the tire hitting the motor).
So I'm thinking a 26x1.4 (or 1.5 if I can find a Michelin brand tire in that size) should be enough to get the tire away from the motor. I don't live in the mountains so the smaller tires I can get, the better my ride will be. :D
Finally got my ebike parts moved over to my mountain bike. This was the bike I have been planning on making electric for awhile. Now that the battery box is small enough to mount onto the rear seat rack and the new lithium battery being light enough for it, this bike is now my primary bike. The old bike was just a place holder so that I had something ride able while I saved up to get the new battery and such. :D
The motor seems able to push this bike along better then the old one. I'm guessing because of the smaller wheels (these are 26 inch wheels instead of 700c) and that it's actually slightly lighter in weight then the old bike. It goes just as fast and now that it's able to handle 2nd gear better, it goes faster then the old bike did. :D
This bike is much more fun to ride and the suspension makes a world of difference. Especially once it goes up to the 23-25MPH range. Pot holes and dips don't scare me anymore and the battery box is mounted above the suspension thus it isn't exposed to as much bumps and vibration. :D
my yescomusa powered bike. Batteries are either 18s2p or 12s3p..
Come see at South Salem Cycle Works tomorrow!
My trike is getting near 100 miles a week on it for pennys. It does 22 or more on just the front hub motor from ampedbikes.com. This design was inspired by atomiczombie.com. The rear end, seat and handle bars are from a Retrike. This creation was built by Tom Sluwka of Eagle Metal Works. All upgraded bearings and tires. Now with twice the range from double the batteries.
The delta design is fast and comfortable.

Hi a vid of my Tonaro Bighit ,crank driven and loads of climbing power.
Hello everyone. This is my trike.
It's a Wes Mason custom racer trike, modified with a city-e-cycles "Conqueror" conversion kit.
It's a 1000watt 48volt motor with a li-ion 17amp battery.
Top speed 25mph
Range 40-45 miles.
It's tempramental and the wiring is cheap, but I like it.
I had to strengthen the forks to cope with the motor and swap handlebars for the throttle.. It weighs 35kg and I weigh 65kg making it 100kg.
I was struck by how similar it is to the very first image in this string from sianelle. . .
Not quite as classy, but we have the same horn and everything!
This trike also has a tow bar. The trailer takes my ruck sack, which means it's the E-bike equivalent of a motor home! If ever you're in the Scottish Highlands, you may see it chained to a gate in the middle of nowhere. I'll be camped nearby.
Hope you like it.

Here is my DIY ebike made from stuff I had in the garage. I ride it to work nearly everyday.
Frame: 1992 Bianchi Main Street hybrid
Crank: Custom made with 96t #25 gear plus 48/38/28t #35 gears with front freewheel
Rear gears: 14-34t Shimano 7spd freewheel
Motor: 24V/500W Currie scooter motor
Battery: 24V/30ah LiFePO4 (16 Headway 40152S cells)
AER: 20-25 miles
Updated the bike- new cranks, old xt drivetrain, hyperglide cassette. I love this thing.
Nest step is to get the controller on the seattube bottle bosses and the battery on the bosses on the bottom of the DT. Weatherproofing is going to be tough, but the weight distribution and clean look will be worth it.
A Giant Twist with a Panasonic mid-drive and a Xtra-Cycle longtail extension. It makes a great cargo hauler.
The sidecar is made from a Burley Flatbed trailer. It takes just a moment to convert it from a trailer to a sidecar and back.
Those are great pictures, AllenG. I finally got to see the ladder on an e-bike. :thumb:
Thanks. I was going through old files and found a few copies. I still can't find the one with the BBQ smoker strapped to the back. Still looking for that.
Can anyone join this club ?
Built my extrabike 4 years ago and today I turned it into an Extrabike... 36V Crystalyte 400 series gives the bike a little boost and the all wheel drive in the snow is totally awesome.
The lead acid / gel batteries are better suited for warmer weather so will be looking to upcycle some Prius batteries to serve me better in the winter although the performance was still really decent over 10 km at -10C in the snow.
The motor has just the right torque to give me a little boost when I need it and is really low drag when it is not under power... an extra 50 pounds on this bike actually makes it ride better... other folks who are bigger than me might want a 48V system.
Will see what kind of range I can get although our lower winter temps are going to cut into that.
That is one hell of a work horse AllenG. Awesome build!!!:)
Thank you, sir.
