Re: Nucular electronics - complete kit for ev! [beta]

Hi Vasili, I am building my 3rd ebike with a 3 kW Mxus hub motor which will be fed with a 20s14p battery. I am looking now for a 72V controller, a 20s BMS, a 20s charger. The 12F nucular seems a good candidate and the price is very competitive. If I understand, the controller is sold with an LCD mon...

Hi Pete,

Where did you get your DC-DC 84v to 12v converter if you have already purchased it? and what is the output power?
Thanks.

Best regards,

I went several through potholes at 30 mph and the rim is still perfect. I also have a SAS 26-inch rim for the back wheel laced to a M...

Re: Em3ev with drop bar commuter - 50 miles/day

Dear ebikers Many thanks for your replies. In the last two weeks, since my last post I added 450 miles on the bike achieved in 8 days. On my 25 miles commute, a third is done in the city. Physical performance improves quickly when you ride 50 miles a day. I limited the max output power of the Mac to...
