This spinning bike defenitely does the job. One downside though is that it is abit loud. i found out it has metal chain rather than a belt after assembling (which is easy and straightforward if you follow the manual) and trying it. However if you’re working out with music that shouldn't be a deal breaker. Another downside is that the range to increase or decrease intensity is not that great. I guess what you pay is what you get, if youre looking for a spinning bike with a low pricetag, does the job, but definitely not close go the one you find in the gym spinning classes; then this is for you.
