Nothing whole and mash

My request is a simple and solid exercise bike for 60 minutes a day sweating. after I'm, like 331100000022 with a folding device Ultra Sport Home Trainer F-Bike with hand pulse sensors, black evil on the nose, a slightly larger model was needed.

the construction Went Potty by hand. The screws are fully numbered and smart sealed in a blister, so that always the right screw at hand. Even the connection of the Bowden cable for the brake setting was simple and not fiddly. Who schonmal a one Fahhrad hooked such a train, is familiar with the procedure. The pulse sensor is fixed with a jack on the computer. Unfortunately, one of the cables is cut cleanly with my device. Perhaps from the packaging at the factory. That would be no drama alone. Unfortunately, there is another serious problem.

I eagerly threw myself into my training clothes and started training. First, I wanted to develop a feeling for the braking effect and drove each gear a few minutes. There are serious deficiencies: In eight existing programs, the gears 1 feel - 4 almost identical to. An increase of the resistance is hardly detectable. Gears 5 - 6 are OK. But in the corridors 7 - 8 of the belt slipping. It is not possible because the belt slips through the vigorous passage immediately to 30 km / h acceleration. At the end of an interval like needs for supplies and even hurt right a few minutes. Here that's impossible, because you step into the void. The bottom line is I have a bike with which I can make a 3-course interval training. This is unacceptable. The noise level is moderate. The bike makes a strong running noise with whom I could live as nothing rattles, crack or rattles.
I am already badly frustrated. The Ultra Sport Home Trainer F-Bike with hand pulse sensors, black, 331100000022 I have returned twice, Weil rattled at all corners and cracked, and now I'd have to patch up to train with three courses a cable. Is it so difficult a simple but at least functioning bike to build? Unfortunately, this bike goes back again and I probably still spend significantly more.
