BG921121715 Since I dont know how to edit the previous review, I would like to add some other details:1.The rear tyre can be pumped, but only with a narrow head hose, not with the typical compact pumps, which -I think- most people have at home. 2.The rear spring had to be replaced due to my weight (100 kg). If the buyer is not a boy anymore - I am afraid - it has be done by others as well. 3.The front spring was very weak. I just placed an additional spring into the original one , so now it seems to work on the ride. 4. The two holes on front are not aligned to the direction of the front wheel . I have seen this problem since then in another review. I do not understand the reason, since it is a too obvious deficiency. They cannot be used on the way. Adjusting other heights and tightening will solve the problem. It is just annoying with this price tag. 5. After riding it for 10 kms I can say it is speedy. Of course with 40 km/h it consumes more energy. The cruise control ensures convenient use. 6. The brakes are great even they are mechanical. I swapped the brake levers. So the front is on the left and the rear is on the right like on bicycles. 7. The head light provides stong beam.
