Looks great! Range and top speed?

[MickMick]

The most I have has is 70mph. I did a 40mph max run and got 33 miles range. I am currently re- balancing the batteries so should get the designed 40 mile range. It was a nice run though. I have a crack in the battery case so need to rebuild it.

Nice! I am trying to figure out what I need for 60 mph, 60 mile range. I was thinking the electric hub, but am struggling to get the battery side for that. If I use a standard 16 inch rime, gives me 24 inch tire, the hub is 10 kwh

[Bikenut]

Should have said the enertrac hub it says it needs 96 volts by 95 amps for 60 mph

[MickMick]

I could get 96v 45ah in mine if it was a hub motor. Or tray and get 60ah at 72v with the space. I should get 40miles on my set up at 30mph, but that would be a bit boring. Lol.

Its all about the battery valence. The pack is only as strong as the weakest cells. Mine only gave out last run due to my BMS allowing one of my cells to drop too low.
