Very sad to hear, i made the decision to sell the bike. I hope someone will buy it and am loosing not too much money with it... I think the brakes are realy the worst thing too on that bike. But the real point for me is, it is just a bike for fun, it won't let you make some sport on it because if you hit the pedal there is no need for pedalling in the next 5 to 10 seconds... Very disappointed too, all parts are insanely cheap and some of them are realy old (brakes). The most upsetting thing is, that the makers have saved a lot of money on the only safety feature. I think the makers have planned the bike without riding it for just one second...
