Can frames be modified ?

[RufusChucklebutty]

I want a bike like this, but I don't want a premium product costing £1000's, i don't get any benefit from high end parts and I only do a couple of rides a week, are there any frame builders that would convert an existing fame to this and how much would it cost ?


Also fancy cutting the BB out and adding a bracket for a Pinion gearbox, but that's another story.

I'd be very surprised if it was possible at all that it would be cheaper than just buying a second hand one.

But I sense from your post you really just fancy having a play!

You'll have to pay, unless you have the skills.

Anything can be modified if you have the skills, tools and or money.

Your trying to do something budget and then mention pinion gearbox. I am thinking that you really do not know what you want.

I'd have thought it was fairly pointless modifying an existing frame. I imagine there wouldn't be much if any cost saving. Easier to start from scratch with the specs you want. There must be a number of frame builders who could do the work for but you're going to need deep pockets .
Alternatively look for a cargo bike new or second hand that might suit.

So you want a frame with longer seat stays.
The cheapest way I can think to build something like that would be to DIY a tandem with a very short distance between the BB's.
It's probably easier to do it that way rather than trying to extend the chain stays on an existing frame.

Luck ...............
