Product Reviews

Ebiketips

When it first landed the Tern was miles ahead of the pack, and was rightly our e-bike of the year in 2018. Skip forward to now and the GSD remains, for me, the pick of the bunch: it’s the most practical bike I’ve ever used.

Drahtesel

Just for [the GSD], a modular accessory system for the weather-protected transportation of children and luggage will be available from 2021: the Storm Box and the Storm Shield.

Cycling Electric

If you buy this as a family e-bike we suspect your main problem will be competition for ride time.

Ebiketips

Tern now offer the Clubhouse fort accessories with the GSD, making a fully enclosed space which means at least the kids can stay dry even if you’re out in the rain up front.
