Turn your 90s steel MTB into something far more useful.
The CarryON is designed and made in East London. It transforms a classic mountain bike into a capable, everyday cargo machine.
Simple, adaptable, and built for real life—school runs, shop runs, or just carrying more of what you need.
The first wave of conversions has been a lot of fun.
We’ve had all sorts through the workshop—different bikes, different ideas, different reasons for building them. From well-loved old MTBs getting a second life, to properly dialled setups built for specific jobs.
Each one ends up a bit different. That’s part of the point.
Cargo Fest in the middle of it all was brilliant.
A proper mix of bikes, people, riding, and general workshop energy.
We’ll be doing it again—a BACK TO SCHOOL version at the end of the August Second Wave.
Get the CarryON front end shipped to you, ready for your local framebuilder to install.
Shipping worldwide.
Join us at the workshop for a full conversion, done by the team who designed it.
Dates: 17–28 August 2026
Location: East London
Because good bikes don’t need replacing—they need reimagining.
CarryON gives a second life to steel MTBs, turning them into practical, versatile cargo bikes without losing their character.
Second Wave conversions are limited and expected to fill quickly.
If you’ve been thinking about it, now’s the moment.
