Spreading my forks

[BGElect]

Hi All,

I'm looking at the options to convert my Dahon Speed 7, with steal forks, to a front hub motor installation.

Having read on this forum about spreading the forks, this afternoon I purchased some 10mm dia threaded bar and gave it a go.

First attempt I went from the original 75mm to 85mm. Then on the second attempt I spread the forks to 125mm and they sprung back to 97mm, close enough to the 100mm I was wanting, so in conclusion it worked and the forks remained central.

Also, one thing to note, the tangs on the end of the forks are soft metal so don't need much effort to bring back to vertical.

Thanks for the advice, all I need now is the conversion kit...

...good point but a Bionx is tooooo expensive and not over here so perhaps a fatter front tyre may help?

A Schwalbe Big Apple should do the trick with no loss of efficiency.

Any of those, just judge on the basis of the lowest you can use with secure handling. They have an enviable reputation and a staunch following and you'll be able to be at the lower end and enjoy plenty of comfort.

Many swear by their puncture resistance too, and A to B like them for their low rolling resistance, so a good all-rounder.
