I bought this a year / 18 months ago, for me it doesn't give enough pedal assistance , or if using the throttle at the higher speed I don't get enough exercise. I've done a 10 mile ride on it with plenty of battery power left in it. Check out the reviews on youtube. I can supply a spreadsheet with all of the settings that can be changed on the bike, including adjusting the top speed. Just 25 miles in total, good condition except for a scratch or two, and needs new handlebar grips, comes with 2 keys, manual, and the tools that came with it if I can find them. These bikes are selling on ebay at anywhere between 750 - 1k.
