Bike received quickly by UPS, proper packaging, I'm happy ... but first disappointment at unpacking: I see a plastic cover of the transmission housing is defeated. I tell myself it does not matter, I will go back on afterwards. Unfortunately, this is not possible in spite of all my attempts ... Unless dismantled the entire casing, that I refuse to do because it's not my place to do that! Second disappointment, much more serious: adjusting the resistance knob turns completely ineffective, almost no difference between one and eight levels! It is therefore impossible to increase éffort pedaling, we always seem to pedal a toy! What good is it to buy a bike cardio if it does not fulfill its primary function: back in shape? All this is unfortunate because this bike, easy to assemble, seems durable and well made. Unfortunately, and I not the only one to say, his big weakness is the resistance adjuster. Finally last disappointment, dimensions when folded: relatively compact in length and width (40 of 40) you still have to specify that the height between the feet and handlebars is 1 m 30, which can be a problem for the store it in a closet., especially that there is no information on the size, on the Amazon site. You'll understand, I was very disappointed with this bike. Fortunately, I want to acknowledge the responsiveness and professionalism Amazon. Indeed, they immediately contacted by telephone offer me a refund and especially to do resume by UPS shipper, saving me a lot of hassle to return it by myself (package of 18 kg anyway! ). Now it's decided, I first try this gear store because too many parameters can complicate your life by purchasing it online ....
