I usually cruising around 20-25mph 99% all the time. No special brakes, I am using Avid BB7 caliper and 160mm disc. My hardtail frame with 140MM travel suspension front fork. That's why I stopped doing speed on my hardtail due too much bouncing on rear tire in high speed. My next 3rd MTB ebike building will be completely treat like an Motorcycle that has full suspension in front and rear end and travel suspension will be over 6" cause I wanted more plushy suspension comfortable on rough or bad roads.
My spokes on both front and rear uses 13g pretty strong enough as long as you readjustment and tune your bike. It pretty secured so far I built new 2nd ebike. Everything runs smooth.
I commuter my ebike to work and home sometime do errands. I saved so much money on gasoline! whoo hoo
@arnie1 The controller's LVC protect just only WHOLE of battery total voltage and NO protection on each cell. Only the one solution is get LVC boards from Gary or Geoff or You homemade the LVC boards that protect each cell.
I experimented the controller LVC set to 42v (15s2p), I discovered one of LiPo went cell 1 =2.73v, cell 2 =3.29, cell 3 =3.28, cell 4 =3.25 and cell 5 =3.28 Total 15.83v. Jesus I almost killed one of LiPo which it did not had balance proper and thank god I was very paranoid that time and felt instinct double check using LiPo monitor happened saw my own eye.
NEVER AGAIN! LVC boards are a MUST have! screw LiPo monitor or alarm and controller's LVC.
