What controller for 72v, 100+ amps?

The Phasor is about to receive a new battery - a 21700-40T pack at 20s6p. I have been advised max amps should be around 105A. Therefore, it also needs a new controller - the existing one is 70A max. The motor is a Mxus 3k. Motor will get fins and ferrofluid The other constraint is the space to place...

Baldwin Street, Dunedin, NZ. There is a warning at the bottom not to try and drive campervans up the street.

Re: Commuting and fun: Ebike Vs E-scooter.

I have a FS mountain bike that will do 40 mph, fairly safely - motorcycle tyres, downhill forks, good quality suspension. I have hit potholes at this speed, without major drama. I also have a 2000W dual motor scooter (60v). It has suspension, but nothing compared to the bike. Top speed is also aroun...

Re: em3ev.com - very disappointed

EM3EV seems to have changed, I don't know why. They are no longer supplying Mac motors, and their available stock has decreased. Just spotted this on their website "200+ MILLION CUSTOMERS; 1800+ TEAM MEMBERS; 24HR SUPPORT AVAILABLE; 99% POSITIVE REVIEWS" which sounds a bit weird. They used...

Re: Sur-Ron - New Mid drive Bike

Yes. Most all 20mm hubs have spacers to adapt to the forks. The ones for the front SurRon hub are sold separately via Luna. Guy might have used them for his SM wheels or they just got lost. They are only held in via o-rings. You need 2 of these: https://lunacycle.com/segway-sur-ron-x260-missing-axl...

I picked up a set of original (new) Sur-Ron wheels, from a guy who put smaller motard wheels on the bike. I have a question regarding the front hub - it is only 80mm. I wanted to use it temporarily in a fork with 110mm spacing while another front wheel is laced up. Are there some spacers that make u...

Re: The downside of more electric bikes

when I lived in Australia, there were no ebike stores I found (Perth) who would look at any of my bikes. Good in a way, because it made me learn stuff I otherwise wouldn't need to.

Re: FOR SALE! New Unit Pack Power Ebike Battery!

There seems to be a bit of miscommunication here. UPP can make battery packs from any type of cells you want. If you don't tell them, they would use Chinese cells.

Having said that, I don't know who Alisa39 is, or how she is related to UPP

Re: Half my EM3ev Order Arrived Today...

looking at EM3EV's website - they offer a 1000W BBSHD or a 750W BBS02. Where did you see a 750W BBSHD? https://em3ev.com/product-category/e-bike-kit-motor/middle-motor-kit/ The motor could be programmed to a max of 25A, if you get a cable and download the software https://electricbike-blog.com/2015/...
