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. The high volume WTB tyres add comfort and mean that you can get off the road and take advantage of bridelways and towpaths. 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 any 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.
