ASSEMBLY: in 1 hour I rode the bike, it's pretty easy and very well signposted. All small parts are there, numbered, even screwdrivers: Can not go wrong.
BIKE: 16 levels of difficulty, it feels good the difference between each. I'm pretty athletic and I start to 9, without forcing it tires anyway. There are 12 different programs, and a function to work the heart rhythm (regular heartbeat, to 55.75, or 95% of maximum).
However, problems: the gourd is done poorly so it is not possible to drink without getting water everywhere ... (Deja found in a previous review!)
And just as the previous comment: the son that connect to ordinteur bike are too short! So they are stuck and broken !! I sent an email to Ultrasport hoping it replaces me that !!
Pay attention: the feet are slightly wider apart than on a normal bike. And saddle, even resolved as forward, is far enough from the handlebars (I think).
Also, it's painful not to have put a battery that retains the data, because we unplugged it loses the date and time, we must réindiquer (or not) on again velo ... And it could help save all user sessions ...
Otherwise very quiet and pleasant bike!
[EDIT]: great customer service !! Two-year warranty, and customer service responds quickly and returns all possibly defective parts!
