B'Twin Folding Bike 20” 6 Speed - Battersea, London

The B'Twin Folding Bike 20" 6 Speed is a compact aluminium folding bike built for urban commuting and city riding. The 20-inch wheels and folding frame make it practical for mixing cycling with public transport or storing in a flat, though the smaller wheel size does mean you'll need to work a bit harder to maintain momentum on longer stretches compared to a full-size bike. The purple colour gives it a distinctive look without feeling overly styled.

The bike is fitted with a flat handlebar for an upright, practical riding position that keeps you visible in city traffic. Stopping power comes from V-brakes front and rear, which offer direct linear pull braking and work reliably in everyday use. The 6-speed derailleur gears with grip shifters give you enough range to handle gentle hills and vary your cadence without needing to search for a wide gear range. The gear lever and derailleur combination is straightforward to use and maintain, though it does mean regular cable checks and occasional adjustment to keep shifting smooth.

Day to day, this is a bike that handles the stop-start rhythm of city cycling well. The smaller wheels make it nimble around parked cars and easier to manoeuvre through congested areas, and the folding design means you're not reliant on finding secure bike parking everywhere you go. It suits commuters who combine cycling with train or bus journeys, or anyone who needs a bike that doesn't dominate their hallway when not in use. The aluminium frame keeps weight reasonable for a bike you might carry upstairs or onto a crowded carriage, making it a practical option for mixed-mode urban journeys.
