I put a 36v controller on one of those motors and it's working well after about 50 miles so far including steep hill climbs. I'm using a small lithium ion battery, you could lighten your overall weight a lot by using a small 36v hover board battery pack (be sure to get one with quality name brand cells if possible, not Chinese cells).
Thanks for the tips. Seems like these little motors can take 36V . Yeah, I'm planning to use lipo packs later on, together with better controllers. I have a 24V 500W version and a 36V 800W one. The 24V controller has 20.5V low voltage cut-off (LVC), while the 36V one has 31.5V. Both are not suitable for lipo packs as they will let the pack voltage to go too low (irreversible damage!). There's so many sellers out there on aliexpress, alibaba etc. Do you have any recommendations?Raisedeyebrows wrote: ↑Feb 19 2018 12:43amI put a 36v controller on one of those motors and it's working well after about 50 miles so far including steep hill climbs.

Search threads by Drkangel on here to learn a bunch about modding and operating those motors, very imformative and I've learned a bunch about using the Currie type motors (which yours is).
Are you leaving the Wood stem holding the handlebars on there or is that for a mockup to make a steel one? Whichever make sure they are secure and your handlebars won't slip while you're riding. Interesting project, good job, I like it!
Here in Malaysia we have abundance of tropical hardwood. Meranti, Jati, Chengal, Nyatoh, Keruing etc to name a few. All have different grains, and very lovely when finished in laquer They are very hard. The Chengal type is so hard that it will split if you even use small nail and termites couldn't sink their teeth into it!Raisedeyebrows wrote: ↑Feb 19 2018 11:43amRemember Lipo packs ( MultiStar etc) packs need special chargers and you need to know what you're doing with them (I don't) because they are have a potential to cause nasty fires and explosive reactions if they are not charged and discharged correctly. A easier alternative would be one of these (very good deal, I bought one):

You could probably ride 10 miles easily with the above battery, I'm doing just that with a 50 lb bicycle with the same motor.
Or there are a lot of 36v Lithium Ion hover board packs on eBay as well, just be sure and find one that claims GENUINE cells, LG, Panasonic, Sanyo etc. Generic Chinese cells are notorious for potential problems and also fire potential.
36v lithium ion chargers are widely available and cheap on eBay, amazon, etc at $4.99 to $20.00, good to have a spare in case one dies at that price. Yeah I like hardwood too, you should see the knife handles I've been making with Hawaiian Milo and Koa recently, together with Japanese AUS-10 blades they are very flashy Paring Knives, very useful in the kitchen. Gave one to my mother-in-law since she bought me a very expensive handmade folding pocket knife last year.
