I bought this bike new 2 years ago . The rear derailer got stuck ok n s fence and broke so I took the chain off. You dont need it . Its full throttle. Tops out at 21 mph . Back tire is flat . $ 10 fix . Im selling because Its making me lazy. Im going to switch back to a regular pedal mountain bike. So Im open to partial trade for a Mountain bike in good condition. Battery holds a charge good as It came new . It has 2k Miles . I never beat on it . Im 53 . Can meet around 207 a nd US1 .NINE0Four eight 15 three nine 62
