Light e-MTBs: The perfect balance between muscle power and motor

Lightweight e-MTBs are considered the most exciting development in the e-mountain bike segment in recent years. They bridge the gap between classic mountain bikes and fully motorized e-MTBs – and are aimed at riders who are looking for a natural riding feel but don't want to forgo assistance on climbs.

But what exactly defines a light e-MTB? Who would benefit from switching? And what are the differences compared to "full-power" e-MTBs?

What is a light e-MTB?

A light e-MTB is an electrically assisted mountain bike that is significantly lighter than conventional e-MTBs. While classic e-MTBs often weigh 23–26 kg , light e-MTBs usually weigh between 16 and 20 kg .

This is made possible by:

smaller, lighter engines
more compact batteries
lighter frame constructions (carbon or high-quality aluminum)

The goal is not maximum engine power, but rather the most natural riding experience possible , very close to that of a conventional mountain bike.

Engines: Less power, more feeling

Unlike classic e-MTBs with 85–90 Nm of torque, light e-MTBs rely on subtle assistance . Typical motors include:

Fazua Ride 60
TQ HPR50
Bosch Performance Line SX
Shimano EP8 RS (race-tuned)

These motors typically deliver 35–60 Nm of torque . That sounds like little – but feels surprisingly smooth on the trail.

Advantages of Light motors:

very quiet operation
Minimal pedaling resistance above 25 km/h
direct power transmission
fine response

You have to actively participate – but you will receive support precisely when things get steep or technical.

Battery & Range: Deliberately reduced

Light e-MTBs have smaller batteries, usually between 250 and 430 Wh . This saves weight, but naturally limits the range .

Typical ranges:

800–1,500 meters of elevation gain in trail mode
40–70 km , depending on terrain, rider weight and assistance level

Many models offer range extenders – small additional batteries (approx. 160–250 Wh) that fit in the bottle holder and flexibly increase the range.

Riding experience: Almost like a normal mountain bike

This is precisely where the great strength of light e-MTBs lies. Thanks to their low weight and reduced motor power, they feel:

agile
playful
controlled
very direct

to.

The low weight is particularly noticeable on technical trails, in tight corners, or when repositioning the bike. Riders also benefit from the improved balance when going downhill.

👉 Those who enjoy active riding and letting the bike “work” will love light e-MTBs.

Who are light e-MTBs suitable for?

Light e-MTBs are not the best choice for everyone – but for many, they are the perfect one.

Ideal for you if you:

are active in sports
coming from organic mountain biking
If you value technology and driving feel
If you want to ride longer tours with moderate support
Looking for maximum control going downhill?

Less suitable if you:

You want maximum support on the mountain
you frequently ride on very steep climbs
transporting heavy backpacks or luggage
you want to contribute as little work as possible yourself

Light E-MTB vs. Full Power E-MTB

feature	Light E-MTB	Full-power e-MTB
Weight	16–20 kg	23–26 kg
torque	35–60 Nm	up to 90 Nm
Driving experience	very natural	powerful motor
reach	less	higher
Trail handling	agile & playful	smooth running & stable

Both concepts have their merits – what matters is your driving style.

Hardtail or fully as a light e-MTB?

There are also hardtails and full-suspension bikes in the light segment.

Light e-hardtails
- lighter
- cheaper
- efficient on forest roads and flow trails
Light e-MTB full-suspension bikes
- more comfort
- better control on the downhill
- ideal for alpine trails and challenging terrain

Most manufacturers are now clearly focusing on light e-bike full-suspension models , as they make optimal use of the concept.

Price level: Premium, not a bargain

Light e-MTBs are technically sophisticated – and correspondingly expensive.

Typical prices:

from approx. €4,500 (entry-level)
€6,000–9,000 in the high-end range

Carbon frames, special engines, and high-quality chassis drive up the price. In return, however, you get a very unique riding experience.

Conclusion: Less e-bike, more mountain bike

Light e-MTBs are not a compromise – they are a bike category of their own . They combine the sportiness of a classic mountain bike with targeted electric assistance.
