  • One reviewer deems the Tero X to be “fairly heavy”.

Bottom line

The Specialized Turbo Tero X range includes three off-road capable e-bikes offering varying torque outputs (50-90 Nm), RockShox suspension forks of varying quality, and battery capacities between 530 Wh and 710 Wh. It’s a highly versatile bike that can cover commuting, off-road and even bikepacking duties. The Tero X’s unified rear triangle suspension is not intended to to keep up with the four-bar linkage setups on performance e-MTBs. But it remains plenty capable, while keeping maintenance simple and prices lower. Some reviewers see the Tero X as filling a gap for non-bodacious e-MTB riders seeking something that can handle rough trails, but where a trail/enduro slayer is not required.

Specialized Tero X Full Suspension E-MTB – Commuter, Adventure and Explorer E-Bike

It’s a commuter, it’s a cruiser, it is an adventure bike and it could be a mountain bike as well… You can definitely go bikepacking with this. I’m gonna pack some camping gear, I have a solar panel and a battery station and a charger so supposedly I’ll be self-sufficient for days.
