Take time to learn how the D11 works best for you under various conditions, and I think it will please you. Want a moderate workout on level pavement? Try a boost of 2 and gear 6. Trying to keep it together on a twisty single track? A boost of 1 and gear 3 should keep you going even in damp dirt. Tired and wanna get home? Use top gear, hold down the throttle for 6 seconds and release it to go 15 mph for 20-some miles on a full charge with decent pavement. Your weight plays a factor given the modest power of this e-bike. Learn to keep the knurled knobs on the handlebar gripper and the seat slide tightener very tight, as tight as you can make them even if you have to use pliers, or your bar soon starts flopping around and your riding position becomes ridiculously low. And Hey, Fiido, thanks for the unexpected fenders, but give us some instructions on how to attach them!
I just ordered the Fiibo D11. It only took +/- 7 days before i got it. Now a couple days further and using the bike daily, i can only say, If you are thinking about buying one, Stop thinking and order it. You won't be dissapointed.
Cover of battery, just under seat is wobbly and controller box is improperly made and water may come in contact with electronics in the box... I can provide you with pictures. I would also like if you could solve this issues.
