Hi. I bought a GT Rider about 2 years ago,done about 1500 miles.the seat tube broke.so i phoned 50 cycle and told them about it.they emaild me back and asked for a picture,so i sent them one,they emaild me back and said i had the the seat post to far out, which caused it to crack.they said it was my fault it broke and i need to buy a new frame.no chance of me doing that.what a load of crap.more like metal fatigue.theres no way would i by another bike of 50 cycles,knor reccommend them to anybody.has anybody had this happen to there electric bike.

All seat posts on all bikes have a minimum insertion distance into the seat tube, if this is not adhered to then there is a risk of frame failure. The problem can also occur where the user has fitted a longer seat post to maintain the minimum insertion distance or the seat post diameter is incorrect I have seen it happen on conventional alloy framed cycles, although not on an electric.

Broken seatposts are not uncommon as Ian has said. You can get extra long and stronger ones if those are required, there's a huge range available in many different materials, alloys, steel, carbon fibre etc.

I don't think 50cycles would choose to dispute such a trifling thing as a seat post, it seems they've just pointed out the cause in this case.

Sorry Flecc. You have misdirected yourself, I think, due to terminology, and syntax.

The "it" refers to the seat tube (frame)

Thanks Peter, I took it to be the common event of the seatpost.

If it's vertical crack, jubilee clips are wonderful things in twos or threes.
