Try test riding a Brommie. Its a compromise ride due to the small fold. Dahons tend to fold in a clumsy manner IMO
Many people do not like the cock pit space, or the handling of the brommie. If you find it OK then its a good solid bet.
IMO Bromptoms only really suit riders under 5' 9. Hense my preference for the rival Mezzo with more cockpit space and easier upgrades.

I have owned all three bikes
