All

Rode mine today at a local sand desert track. I'm no expert, maybe slower b class on a good day. Started the day at 100% and finished with 7% Got about 1hr 40mins of ride time before needing a charge. I can see an A class rider especially on sand go through battery pretty quick but I'd still think it would last atleast 30 mins. For a fast A class or pro rider this is not the bike unless you want to be charging all the time. And this was all in 42hp with 25% regen.

Sorry for confusion, I meant I’ve never had the issue you described with the light even when I’m riding sand moto. I completely agree with you, I truly don’t understand why everyone has such different experiences. I weigh 155lbs.

I would try a scoop tire if you haven’t it may help some. If you get better traction you may reduce the speed at which the motor is turning by a measureable factor. Less motor speed /more drive = less heat.

There are 12 temperature sensors inside the battery, six per side. It will limit on the hottest sensor. If one of them is problematic (reading a temperature significantly hotter than actual temperature) that will cause it to falsely limit. It will limit because it thinks the battery IS hot, not because it thinks the battery will BE hot. The prototype bikes ran Molicel P42A. With those cells the weak point (thermal wise) was generally the battery. The batteries actually sold use Molicel P45B. With those cells the battery was generally no longer the thermal weak point. I say generally because...

The thing I hate the most about the electric mxbike community is that everybody is lying about the real performance of the bike. I built a custom electric Honda and I have overheating problem. But I go on diy ebike forum everybody says it is not possible etc. The specs of my bike are very close to those of the stark. I can get 80hp out of it too. But the overheating is the problem.
