Stunt pegs on a mountain bike

jjl5590

Hey guys,

I plan on taking my Saracen X27 mountain bike to university with me next year. I'll be living with 2 others, 15 minutes away from campus.

I was thinking, would it be possible to somehow attach stunt pegs (such as on the rear of bmx bikes) so that I could carry a passenger on the back of my bike? It would be extremely useful

I believe the frame is made of aluminium, so I'm guessing I would need to weld two pieces of aluminium pipe to either side of the frame.

Has anyone ever done this? Any advice?


Many thanks!

Not designed for it, I wouldn't bother! You'll bust the frame.

Only way would be to fit a solid rear axle and pegs that attach to these, but even then BMXs use bigger axles than MTB.

Well yeah I know it's not designed for it, but being an engineer and all I figured I could weld a pair of tubes either side of the frame. It's a pretty damn chunky frame, and I've tested it's strength (two people bouncing up and down on the part of the frame where I plan on attaching the tubes), and it's held up fine :?

I wouldn't worry about it. It's your mates knackers that will meet the back wheel when it goes wrong, not yours.

And do still bend! I defo wouldn't risk it on an MTB.

Being an engineer and all that you did consider things such as the extra leverage ratio a set of pegs would have on that part of the frame, that if you weld it to just one tube it's a rotational force rather than a torsional (I believe) force and that with it being an aluminium frame it'd need to heat treated again otherwise it'd become a brittle and weak part of the frame

This idea is on a par with inflatable helmets and the bike backpack

Hell its nearly as good as some of my ideas!!

I used to have grindpegs on my old Marin, used them when messing about at the skate/BMX park, as well as messing about carrying mates.
They were fitted to the axle though, like they should.

What would it be useful for? Wouldn't it be easier for your prospective passenger to get a bike of their own? If you find yourself taking a passenger home, why not just walk the bike? In particular, I can see this sort of exchange going on:

Prospective passenger : When you offered me a lift home, I kind of expected you to have a car
You : I done welded them pegs meself <spits>

Also it's against the law, but the "doesn't make much sense" argument comes first

oodboo

How about you weld another bike onto the back of your bike?

Admins - please move this to the CC, pretty please...

holy wheel reinvention batman

man, if only somebody could invent some kind of motorised bicycle... we could call it the "motor cycle".


is there a need for a "classics" subforum?

I had the same thought
