Choosing between 16-inch and 20-inch wheels
Wheel size significantly affects both fold dimensions and ride quality. This comparison helps you understand the trade-offs.
Fold size
16-inch wheels enable the most compact folds. Brompton, using 16-inch wheels, folds to approximately 585 x 565 x 270mm.
20-inch wheel folders typically fold 20-30% larger in volume. This affects storage in tight spaces and positioning in crowded train carriages.
Advantage: 16-inch for compact fold.
Ride quality
Larger wheels roll over bumps more smoothly, maintain speed with less effort, and feel more stable. 20-inch folders ride noticeably better than 16-inch alternatives, especially on imperfect road surfaces.
16-inch wheels accelerate quickly from stops but transmit more road feedback. Longer rides may feel more tiring.
Advantage: 20-inch for ride quality.
Speed and efficiency
On flat, smooth surfaces, both wheel sizes can achieve similar speeds with appropriate gearing. The difference emerges in efficiency: 20-inch wheels require less effort to maintain speed over distance.
For commutes over 5 miles, the efficiency advantage of larger wheels becomes more noticeable.
Which size suits you?
Choose 16-inch if:
- Train commuting during peak hours is regular
- Storage space is minimal
- Commute distance is short (under 5 miles)
Choose 20-inch if:
- Ride comfort is a priority
- Commute distance is moderate to long
- Storage allows for larger folded package
