I enquired to Alta about how their bike would go in a flat track event with 700M straights for 4 laps, thats about 18 seconds flat out followed by 5 seconds braking. They told me that it wouldnt last as thermal limiting would slow it down after 2 laps. Has anyone ever experienced the thermal limiting on their Alta (or someone else's Alta)?
If won't occur until I go through 3-4 ride-charge-ride-charge sessions.
It gradually cuts the power output, but will never completely "shut off"

I suppose it depends on what sensor heats up the quickest and triggers it.
You could try to get it as cool as possible before the start and maybe it’ll be fine?
If I don’t charge I could ride in map 4 wide open from full - dead battery without ever hitting the thermal limiter.
It only occurs after continuous ride/charge cycles where the battery never gets a break to cool.
In the Midwest we often ride at 40° or sometimes a touch colder even on sunny days. Hand guards and hoodies are good tools to stay warm. However... is it really that bad to ride the battery under 50°? That’s the only chink in the Alta armor I’ve found yet- given that some of our very best riding days happen well under 50°.
Post a reply to: Alta thermal limiting....Any one notice it before?
