For what yo get right out of the box for just under 3000 bucks, there is absolutely no buyers remorse. I can easily lift this bike in and out of the truck bed of an F150 height. I certainly reccomend buying the fenders that go with it. As for any other upgrades to add to is up to you. Maybe an extra set of tires and tubes becase you'll need them sooner than later if you really get after it on this thing. I ride it pretty hard and use a lot of its power and I get 30 miles out of it with some to spare. Both Surface and Bike Berry delivery high quality customer sevice. I give the bike four stars because it is not perfect and each model year has improved. My reccomendation is drop the camo paint job because it flakes off. Give it a real paint job in cerakote. The bike did show up with a broken reflector and faulty headlight. Customer service quickly took care of this. If you are 5 Foot 6 inches tall you can ride the size M/L frame with no issue. I originaaly ordered it size S/M. After placing the order I was informed that the small medium size was out of stock till April. I was asked if I would like to wait, try size medium large or another bike. I sized up and have no regrets. My next ebike will be a fat one that has duel hub motors.
