20" fork and rear triangle available using the original Brompton main frame. Lots of photos on Instagram.
1. Accepts wide 406 20" tyres
2. Disc brakes
3. Folds like a regular Brompton
4. Obviously it is slightly larger
5. Steel only construction

I've had a conversion on my short list since Vincent prepared the prototype last year...
