Montague Full-Size Foldable Mountain Bike.

With a flat bar handlebar, 26-inch wheels, and a sturdy alloy frame, this mountain bike is designed for off-road adventures.

Useful as an occasional commuter bike, it's also handy to get into a car boot without the need for a special bike rack (you'd need a good sized boot).

Gears and brakes all work well.

Overall it's in good working order.

I'm retired now so never need to take it on a train again.
