Bests & Worsts Reviews from Amazon

The bike seems great at first. It's relatively easy to assemble, is fairly sturdy and quiet (initially). However, after riding for 25-30 minutes, particularly at higher resistance levels, the wheel begins to make a very loud clicking sound. I had returned my first bike to Amazon after this happened on my first ride, thinking it was defective, but had the exact same issue on the replacement (again on the first ride)! The housing gets pretty hot and the wheel inside seems to warp and spin off-center, scraping against something inside. Maybe this is fine for very light exercise for short periods, but clearly this is not well manufactured. While the price may be appealing, you definitely get what you pay for.
