Just took my Rize RX 2021 out in Montréal in -12c (-20 with the wind) every thing seemed to work well until I got the a junction and had to stop. I had to apply a lot of torque to get going again. I thought for a while it had switched off the motor assist but it did eventually fire up after about 15 secs. But it was a similar problem at each stop. Anyone else had this problem in cold conditions?
