Depending on the frame you use some older bmx necks and bars are smaller and not easily compatible, I have sleeved bars before and ran bolts thru to overcome this delimma. Beware raising a neck so high it can snap with the fork tube. A larger front wheel and smaller rear wheel can aid the...

Super cool info! This is what I need to stick all my loose 18650s into for a Rocket Pocket!

What was the cost to build roughly? from Pagosa

As a newbie I had an assumption a larger motor and/or contoller would achieve better performance with a 36v battery, but a larger motor must have more voltage to improve and a larger controller has a different LVC(low voltage cut out) which limits the voltage aquired from a smaller battery.

The learning wires(white) arent plugged together are they? That will override the throttle and must be unplugged to disengage.

DD motor seems it could handle brief spurts of a higher voltage to achieve an ultimatem top speed greater than what a mid drive could handle voltage wise,a pure guess, but sounds like middrive for the steeps:)

Hoverboards are cheap, can be found used on Walmart.com, Craigslist, even on the curb. Both 6.5" wheels are mini DDmotors, plugged to an ebike controller they go crazy fast. They plug in just like ebikes and for between $50-100 you will have two motors. A 3 phase bridge rectifier will turn the...

I have been salvaging motors from junk and know I few tricks. The washing machine motor is a complicated fabrication, I have a couple. My McGyver advice is to use either a treadmill motor or 110 lawn edger motor with pulleys and belt drive if you are set on a DIY motor. Tractor Supply Co. has...

Hello from Texas, I am a novice ebike builder with 4 DIY builds currently. Two of my builds have 20" rear DD hubs with a 26" front wheel. The smaller rim feels a touch faster and accelerates quicker with my 36v batteries. In addition I used BMX bars to raise the front further! I recommend this...

I have seen a gas powered track bike at Wolf Creek Ski Area, with a ski for the front wheel. This thing looks fun if it doesnt sink too deep. Maybe 2 ski front wheel would help or a side ski katamaran style could keep it afloat.

If you use the learning wires after plugging in your controller, then you unplug your controller, you may have to relearn the controller again when you connect your wiring. If you apply full throttle to a controller which hasnt 'learned' you can fry it.

I take my DD hub ebike to CO. in the summer and the hills eat up the battery super quick and the torque is real bad. I have never owned a middrive but know a friend who beats dirtbikes using one on steep hills. A 20" wheel will help the torque but I still get sad when feeling the limits of a DD...

Howdy, I am having difficulty adding pics to the forum, if youd like I can send a pic to your phone. I want the forum to know a belt drive treadmill motor is a functional DIY alternative. Mick

Like E-HP said, pedalling a motor around with NO power will have double the resistance due to magnetic cogging and may not be ideal for longer rides. But ebikes are an addiction and the bicyclists who hate on them dont realise what they are missing! As said before, get the biggest battery you...

I have seen vids where heavy equipment users have repaired tires by filling with 'Great Stuff' Gaps and Cracks spray foam. I want to experiment on a cheap wheel.
