Looking for a way to do some exercise to maintain health, while avoiding outside inconvenience especially with winter coming, I opted for this bike so most of the comments already present m ' had convinced !!! Received quickly by UPS the next day! the product is well packed, easy to assemble if you take your time to look well supplied schema. To use I was really surprised by its silence, good grip and stability !!! pedaling speeds ranging from 1 to 8 or contrary to what I read on some reviews seems quite correct one feels the difference especially for someone who is not be sporty, be moderate sports like me, lé for pro cycling way round France lool going your way ... I therefore 1m85 in height with the saddle at the last level I sit perfectly, to the weight 78kg I therefore very bearable because I believe that this bike can withstand 105kg jusqua, which may be limited for some! So very good buying level taken Quality, quite sour held on time ...
