Calibre E-Lost Lad Electric Bike

The E-Lost Lad is designed to make light work of adventures and commutes. When you load a bike up with bags it can become heavy and cumbersome - the addition of the 250W Promovec hub motor means you can take the struggle out of the ride and enjoy it.

High volume WTB tyres add comfort and mean that you can get off the road and take advantage of bridleways and towpaths too. The wide, flared handlebars are designed to put you in a controlled riding position and the relaxed head angle gives you the confidence to ride over rough terrain.

When it’s time to charge, the battery can be left on the bike or easily removed and charged away from the bike.

Feature Highlights

Gravel Bike design – More comfortable and versatile than traditional road bikes.

Large 7.8AH battery – Enough power to do long rides on one charge.

Promovec 250W hub motor – Plenty of torque, even when loaded with bags.

WTB Horizon tyres – Wide and grippy enough to tackle the roughest tracks but also roll fast on the road.

Rack and pack mounts – Fixings that enable you to load the bike with bags for multi-day adventures.

Shimano Claris drive train – Decent shifting and reliable performance in an 8-speed package.
