Overview
An 8-speed folding bike with a brushed alloy frame, aluminum V-brakes and compact wheels built for multi-modal commutes that mix pedaling with a bus or train leg.
The recurring problem isn't the bike's design so much as how it survives shipping: multiple owners describe a bent derailleur hanger, an untrue rear wheel or broken fenders on arrival, and Dahon reportedly requires a bike shop setup to activate the warranty.
- 8-speed SL-M315 trigger shifter
- Aluminum 110mm V-brakes
- Brushed alloy limited edition finish
- Compact wheels for portable folding
Pros and cons
- Folds compact enough for a car trunk or small apartment
- Rides close to a standard bike once set up
- 8-speed shifting handles flat commutes smoothly
- Comfortable adjustable ride with good handlebar grips
- Multiple reports of shipping damage, from bent derailleur hangers to broken fenders
- Warranty setup reportedly requires a Dahon dealer, which may be far away
- Not the lightest or smallest folding bike when packed down
Performance notes
The compact wheels and folding frame are what make trunk or apartment storage realistic, and the 8-speed SL-M315 trigger shifter handles flat terrain commuting smoothly per riders. Because Dahon's folding hardware uses proprietary parts, any shipping damage to the derailleur hanger or wheel truing generally needs a Dahon dealer rather than a generic bike shop.
