The Pink Mouse

Thank you dasilvarsa, these bikes can take 180 kg I checked the specs. I think the heavies on them is are around 120kg at most. Yes that what I was thinking more to do with the bearings wearing and cheap equipment. As I said before these are NOT cheap commercial bikes so cant see that the axle or cranks can be rubbish. I definitely am not doing that crazy swinging around on them. Only what one would do on a road bike, peddle or stand up.

Tell us more on the interesting things gym staff have told you ! I've changed the movement slightly, to accommodate the gym. Will definitely do a bit more investigation. I certainly don't do stupid things on the bikes & have never ever had problems.

My thoughts exactly !!!

I don't have any pictures. I was told this by the gym management, that certain excersises, we are not allowed to do, as it will bend the cranks. So just wanted to know if anyone else had this experience. As I thought it rather a strange claim. My first road bike is an antique & had been through a few crashes never ever any problems with it, apart from the chain. My spinning bike at home not top of the range, no problems there either.

Thanks LongDonkey, it's been baffling me. Yes a friend of our has all 5 track titles a very big man & I believe he has bent cranks but not the axle. Maybe they referring to the axle but even then, the only way to bend the axle is if they are cheap rubbish or by dropping the bike or doing something stupid & the person is 200 + kilograms doing some really hectic hip hop moves. ‍ I checked the bikes limits and they can take up to 180kg These bikes are not cheap, something in the region of $4,500 Being commercial bikes they should be able to withstand a bit more punishment than the Game home spinners.

I am a spinning instructor at a gym, I have a spinning bike at home & have had it for at least 10 years + now. No issues with mine either not cheap bikes but not top of the range. Been riding bicycles for over 30 years & husband for over 50 and all our equipment is still 100 %. So was just for interest sake wanted to find out how it would be possible to bend cranks. I was told by the gym manager, not to climb on the bike with one peddle but to sit on it and then put your feet in or go back over the saddle with heels down to stretch the calves as by standing on the peddles the crankes will bend as they have had problems in other gyms. I can only think either the weight was over the bikes limit and they were doing some sort of hip hop on the bike or they have very cheap cranks on. ‍♀

I am asking as I was told that by standing on both peddles the cranks get bent, so want to know if anyone else has had experiences of cranks bending in a gym and why. I have ridden bics more than half my life from spinning bikes, road and mountain bikes, never heard of cranks bending because of standing up or how one climbs onto it. I feel they then have cheap cranks in or someone over 200kg on the bike. Don't see that a 65 kg person could bend cranks.

Is it possible to bend the cranks on a spinning bike if so how ?

When I started riding it was on men's bikes, men's shorts & yes I suffered really bad that even water hurt but then that's what there was. Riding long distances with many hours in the saddle with the saddle slightly tilted down in the front, yes it helped but still rubbed raw. I then started making my own chamois in my shorts, it all helped !!! ( woman do not need the stitching that all comes to a point in the middle as it was in men's shorts, that was just the wrong spot to sit on for woman) thank goodness we now get women's shorts. Eventually I got a woman's pacific bike, what a difference it all made, with the right saddle, saddle tilt & bike fit it all helped and problems gone. My saddle was never a soft one always hard. So get the right bike fit/position, the right saddle, shorts and then spend many,many happy hours in the saddle.
