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. Reviews range from praise for its fold and ride quality to reports of shipping damage on arrival.
Dahon's pitch here is portability without the bike feeling like a toy, and several reviewers who own their first folding bike say it rides more like a regular bicycle than expected, sustaining around 13.5 mph on flat terrain with light effort. 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.

What buyers say
From Amazon customer reviews.
Riders who set the bike up properly describe a smooth, comfortable commute, with one sustaining about 13.5 mph on flat terrain and another surprised at how close it feels to a standard bicycle despite folding compact enough for an apartment. The recurring complaint is shipping condition: reviewers report a bent derailleur hanger and untrue rear wheel, broken fenders from what looked like rough handling in transit, and the added cost and inconvenience of a required bike shop setup to activate the warranty.
Strengths and trade-offs
Drawn from this product's published specifications.
- 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.
