Our recommended commuting bikes, that pass all those above tests, include:
The Vado SL Range By Specialized
Lightweight and supremely smooth, there will be few ways to get to work with as much fun and style as a Vado. Even if you forget to charge up your Vado – which would be exceedingly rare indeed – it is a lovely bike to ride even without power.
The MiRider
This bike would be particularly good for taking on trains. While other electric bikes are a little hefty and cumbersome for this purpose, the MiRider is the most compact and neat electric bike that we have found; even more suitable for carrying on trains than the famed Gocycle.
