Mountain e-bikes

E-MTBs for trails, fire roads, and steep hill commuting.

What should you know about mountain e-bikes?

Mountain e-bikes (e-MTBs) are built for dirt, gravel, and trail terrain. We compare motor and torque figures, suspension, brakes, and gearing from each maker's published specs, checked against owner reports and third-party tests where they exist. Most owners ride a mix of road and trail, so we weigh both.

Our catalog at a glance

We have reviewed 37 mountain e-bikes, priced from $249 to $1,999 at MSRP. Motors across the group run 500–6000 W with 250–2080 Wh batteries. Wattage above 750 W is almost always the peak figure a brand advertises, not the nominal rating that decides class — the federal low-speed e-bike definition caps nominal output at 750 W, so check the spec sheet before assuming a high-wattage bike is street legal where you ride. Manufacturer-claimed range spans 15–60 miles — claims measured at low assist on flat ground, so treat the low end as the realistic figure. Weights run 48–110 lb, the lightest being the Qlife Racer 21-Speed Electric Mountain Bike at 48 lb. Rated payload spans 265–500 lb. By US class the mix is 7 Class 3, 4 Class 2 — which matters because Class 3 is not street-legal in every state. The cheapest we currently rate is the Qlife Racer 21-Speed Electric Mountain Bike at $249. Our highest-scoring pick in this category is the TST Fat Retro, which leads on our editorial score. The list below puts proven Amazon best sellers first, then our score, and never ranks on price or commission. Figures above come from each manufacturer's published specification, recorded when we reviewed the bike — they are not our own measurements.

Prices are subject to change, and the buy links always fetch the live price. Motor is the figure the listing quotes, which is often a peak rather than a rated number; US e-bike classes are set on rated output. “Not stated” means neither the listing nor our review gives a figure.

All mountain e-bikes we've reviewed

Best sellers first, then our highest scores.

E-MTBs split into hardtail (front suspension only, lighter, cheaper) and full-suspension (front + rear, heavier, more expensive, better on rough trails). Mid-drive motors (Bosch, Shimano EP) climb better than hub motors but cost more. For UK + EU riders, EAPC compliance caps motors at 250 W and 25 km/h — international SKUs unlocked to 28 mph cannot legally be ridden on UK roads.
