Hi,
I use my bike to comute about 25 miles a day. I can drive about 43 miles with 1 charge this in mixed stands mostly 2 or 3.
In 1 I can drive about 28 mph in 2 about 40 and 3 I reached max 56 mph. I am 1m 83 and weigh 76 kg.
For me it would be ideal if 1 and 2 were 3 miles higher, because now i am slowing down the traffic a bit.
From 0 I get a better top speed and sadly when driving already the acceleration lacks a bit. Not the same power as when I accelerate from 0.
All have been driven in cold weather 11 °c max.
But all in all for a 3 kw motor and the price I am more than happy.
Would certainly recommend the bike to anyone who is interested in buying a light electric bike.
I'm not an electrician, but we can expect battery sag as voltage works its way from top voltage to low. The controller limits amps not volts. So as voltage drops so does available amps at each setting. Level 1, I get 60km plus down to about 70% charge, then 55km max continues through remainder of battery. I'm no slim Jim at 125kg. The bike is so much fun to ride. Enjoy
