Cheers. I wouldn't have the faintest idea on range etc on this build, the gearbox never lasted longer than 5km before stripping teeth off as per the pics above... Actually thats a good point for anyone considering using a BaneBots gearbox - don't!
They are cheap yes but they just can't handle any decent amount of torque or shockloading. You'd be better off getting a PLE80 sized Neugart planetary gearbox like the brand new 5:1 model i've just bought to rebuild this bike with (this time with an 80-100 outrunner instead of the Astro 8150). The PLE80's have a proven track record of standing up to decent sized outrunners and off road riding too (Burties Stinky comes to mind).

I am curious if a person finds a frame that is a candidate for such a project are you having to worry about the series of aluminum that the frame is made of or do you just go for it with the 6061 stock for the customizing and weld it to whatever the frame happens to be made of. My guess is that 6061 would work with most Aluminum frames but I am not sure.
The Norco frame itself is 6061. The sides i used were 12mm 5083 marine grade plate machined down to 5 and 10mm and the top plate was 3mm 6061 sheet. I'm pretty easy going and adventurous when it comes to welding different grades of ally together, but i figure if you over engineer what ever it is your joining, you can usually get away with it. At work we normally only use 6061 sheet, plate, tube and rhs/shs. With the exception being some 5083 from time to time. 6061 will normally play nicely with most grades.

Yup, that happened on several occasions, normally after about 3 - 5km of riding - i never got any further without busting the planets!
I ended up buying several sets of spare planets and chewed through the whole lot before giving up on the Banebots gearbox, it was just too cheap, nasty and made of cheese!

Lol. If only the bike sounded like a turbo on song i'd be a happy camper... its from a mate's old Nissan CA18DET we squeezed into a Datson 1200 ute
A young guy bought the ute, rebuilt the engine with a biiiig TO4 based turbo, forgies, prog computer etc and a ford 9" diff. Lag city but it runs mid 10's on the strip..
