Product Reviews

The biggest deal with [the Vektron] is that it features a high-quality gold standard Bosch electric drivetrain [...]. It's well worth reading our page on electric bikes, highlighted above, to understand why the battery and motor choice really make a difference on ride quality of e-bikes, but in summary: you get what you pay for.

Cycling Weekly

The Vektron is the Mercedes S-Class of electric bikes. It’s beautifully built, with a high-quality feel to all of the mechanisms. It’s extremely comfortable to ride, even over longer distances, thanks to a strong motor and 10 gears that make hills a breeze.

Auto Express

The [Vektron S10] 'pack mule': Great everyday suitability thanks to a wide range of luggage carrying options. Absolutely safe handling.

Auto Touring

It’s not super often that I ride a folding bike and am able to forget it’s a folding bike. (...) The Tern Vektron S10 is a rare exception to this rule.
