I reached 122 km speed up to 30 kh with full 100% battery have traveled 19 kmI think you can get to 20 but certainly not to 30/35 KmI'm having a problem getting 20/22 kmh feel unstable pedals, do not push me up and pitching down.It this happens more from the side of the 'switch.I did leveling but still this way and goes to increase when the battery is below 50 percent.dall 'side each other goes a little better, and this appears to 24/25 kmhthat does not do it always makes me think of a power out
