I ve had the Moscow plus for about 2 years now and always thought it just didn't have the performance and zip I 've always wanted with an ebike. So i found a volt booster. I spliced the battery wire in the frame, fed a cable to the booster that I mounted on my bike rack the spliced the power cable that led to the controller and attached it to the booster. on the booster there is a low voltage cut off , constant current and volt booster potentiometer. I boosted the voltage just shy of 60v to 59.3 , adjust the amperage to just shy of 15 amps. (controller is a 15amp controller) then took it for a ride. I noticed right away my take off had 10x more power but as soon as I started coasting the controller kicked in and it would go back down to 32km an hour. Well ladies and gentlemen, when I changed the wheel size down to the lowest one with the power profile on max, i must of been hitting nearly 50km an hour and pushing 700 to 900 watts. I was flying like a bat out of hell, i kid u not it seemed that i wasn't burning as much juice then i expected. my range is better because it pushes the full wattage it can until you let go of the throttle. so alot of times im just coasting. so adjusting the tire size to bigger makes it less powerful, or adjusting the power setting to eco makes it push about 600 watts continuous . i know that I am going to burn out the motor twice as fast but for the $250 cad price tag its well worth it. what a relief now I am not impeding traffic and can get somewhere in actual good time.
