The assembly of the two arms connecting the seat to the record is not that obvious (I put 30 mins to mount the seat in total..après I not ride every day ...) The tissue is stapled under the seat properly, the white outer seams have been doubled if not a bit less aesthetics, 5 wheels works well when the foot 5 branches it is not oversized and show confidence when in stability. I think it is you avoid sitting there naked torso for not dauréole the folder. !! Attention !! when the description on the tilt lever switches the seat and back, it's not just the folder that tilts ... is it really wanted or what is the system design is simplified I shall not say .. Comfort: the seat is a bit hard it is rather reassuring to see over time, good hold back the moment we are in the hold of the seat (I measure 1.76) The armrests are comfortable is quite short thereby pass under a desk shelf
