Hi, Im Luis from JuicedBikes. Glad to hear you tested one of our bikes; which dealer did you visited?
Some of our users have reached to us regarding this "sudden shutdown" event. In resume i can say that its user dependent because it is a protection programmed into the system in case of overheating due to high power demand and high temperatures in the environment.
Ill quote Tora as he is actually addressing this and other items in order to keep developing a great product for us all
" This event can happen in certain situations like hill climbing.
The system needs to cool down as the temp sensor sees high temp and shuts down for a moment to cool down. We found that there is some variation of the temp sensor.
With better transfer of heat away from the body of the controller the issue is less likely to occur.
We are using thermally conductive tape and a strip of aluminum to transmit the heat right to the frame ( not tin foil). The effect is quite dramatic. We study it a lot and better understand the issue on the production units.
These new controller integrated into the bike frame designs have more limited ability cool down. Additionally we run it at 48V when most run at 36V with momentary over-boost function.
Our bikes can really assist up to 28mph And a over boost function maybe we could program it to be less easy to trigger.
The controller and motor is designed to handle the power, but physically could be better positioned so the heat can get dumped away from the controller faster.
All production units moving forward have been improved. And we will keep improving the product so it's constantly evolving.
And if someone frequently encounters over heat warning we can supply them with the part and instructions to improve it. "
Hi Luis, thx for the info from Tora. I have a Crosscurrent in route to my LBS that I just purchased. Is there a way to determine whether my unit that i will be receiving has the fix already done on it?
