- Wheels: 29-inch front / 27.5-inch rear
The Cannondale Moterra SL 1 combines full-power assistance with a chassis designed to reduce the weight penalty common to traditional full-power eMTBs.
Its custom-tuned Shimano EP801 motor provides 85 Nm of torque and more than 600 watts of maximum output. The internal battery stores 601Wh.
A 160mm FOX 36 Factory fork and 150mm of rear travel give the Moterra SL enough suspension for steep and rough trails. The stock mullet wheel setup uses a 29-inch front wheel and 27.5-inch rear wheel.
Cannondale also provides multiple assist modes, allowing riders to reduce support for range or use stronger assistance when required.
Compared with the Amflow PX, the Moterra SL has lower peak torque and a smaller battery. Its main appeal is a familiar Shimano drive system combined with aggressive trail capability.
How to Choose a Lightweight eMTB
Compare Weight and Motor Power Together
Complete-bike weight affects handling, especially when changing direction, lifting the front wheel, jumping, or moving the bike through technical terrain.
Motor output changes the other side of the equation. A sub-40-pound eMTB with 55 or 60 Nm of torque serves a different purpose from a 45-pound bike with substantially stronger assistance.
A useful comparison should therefore consider weight, torque, and battery capacity together.
Riders who prioritize agility may benefit more from saving several pounds. Riders who regularly climb steep terrain may accept additional weight in exchange for stronger motor support and a larger battery.
Choose the Right Motor Torque
The motors in this comparison cover a wide range.
The Specialized Levo SL produces 50 Nm. The Pivot Shuttle SL-AM produces 55 Nm, while the Yeti MTe and Trek Fuel+ use 60 Nm systems.
These lower-torque systems suit riders who want noticeable assistance while still providing substantial pedal input.
The Orbea Rise can reach 85 Nm in RS+ mode, and the Cannondale Moterra SL also delivers 85 Nm. The Amflow PX reaches up to 150 Nm of peak torque.
Higher torque is most useful on steep grades, technical climbs, repeated accelerations, and rides where stronger support is a priority. Lower-torque systems generally preserve a more pedal-bike-like character.
Compare Battery Capacity
Battery size affects stored energy, range potential, and bike weight.
The Yeti MTe T4 uses a 290Wh battery, while the Specialized Levo SL uses 320Wh and the Pivot Shuttle SL-AM uses 400Wh.
The Orbea Rise offers 420Wh or 630Wh. Trek uses 580Wh, Cannondale uses 601Wh, and the Amflow PX uses 700Wh.
A practical buying framework is:
- 300 to 450Wh: lower weight and shorter rides
- 500 to 650Wh: balanced capacity for longer trail use
- 700Wh and above: more stored energy for long rides or frequent high assistance
These ranges are buying guidelines, not official eMTB categories.
Manufacturer range figures should not be compared directly unless test conditions are similar. Elevation, rider weight, terrain, tires, assistance mode, temperature, and speed can all change real-world range.
Match Suspension to Your Terrain
Suspension travel determines much of an eMTB’s intended use.
The Orbea Rise SL uses 140mm front and rear, making it suitable for general trail riding.
The Trek Fuel+ EX moves to 150mm front and 145mm rear.
The Amflow PX, Pivot Shuttle SL-AM, Yeti MTe, Specialized Levo SL, and Cannondale Moterra SL use 160mm forks with roughly 145 to 150mm of rear travel. These setups provide more margin on steep, rough, and technical terrain.
More travel also adds weight and can reduce efficiency, so suspension should match the trails you ride.
What Is Considered a Lightweight eMTB?
There is no official industry-wide weight limit for a lightweight eMTB.
For practical comparison, the current market can be divided into three broad groups:
Under 40 lb: Ultralight eMTBs that place a strong priority on minimizing total weight.
Around 40 to 45 lb: Lightweight eMTBs that balance low weight with useful motor assistance, battery capacity, and trail suspension.
Around 45 lb or more with full-power performance: Lightweight full-power eMTBs that carry stronger motors and larger batteries while remaining lighter than many traditional full-power models.
These ranges are editorial buying categories rather than formal technical standards.
Lightweight eMTB vs Full-Power eMTB
Traditional lightweight eMTBs reduce weight mainly through smaller motors, smaller batteries, lighter frames, and lighter components. Their main advantages are agility, easier bike movement, and a ride character closer to a regular mountain bike.
Traditional full-power eMTBs usually carry stronger motors and larger batteries. They provide more climbing support and stored energy but often weigh more.
Lightweight full-power eMTBs sit between these categories. They use stronger drive systems and larger batteries while controlling overall bike weight more aggressively.
Choose a light-assist eMTB for low weight, natural assistance, and active handling.
Choose a lightweight full-power eMTB for stronger climbing support without moving to the heaviest eMTB platforms.
Choose a traditional full-power eMTB when maximum motor support, battery capacity, and planted handling are more important than low weight.
FAQs About Lightweight eMTBs
Are lightweight eMTBs worth the higher price?
They can be. Premium lightweight eMTBs often use carbon frames, compact drive systems, lighter components, and weight-optimized batteries. The extra cost makes the most sense for riders who value handling, easier bike control, and lower total weight.
Can you ride a lightweight eMTB with the motor turned off?
Yes. A lightweight eMTB can still be pedaled without motor assistance. It will remain heavier than a regular mountain bike because of the motor and battery, but lower-weight models are generally easier to pedal unassisted.
Are lightweight eMTBs suitable for bike parks?
Some are. Models with 150 to 160mm forks, capable rear suspension, strong brakes, and suitable tires can handle aggressive descending. Always check the manufacturer’s intended use and bike-park rules before riding lift-access terrain.
Do lightweight eMTBs fit standard bike racks?
Many do, but rack compatibility depends on bike weight, wheelbase, tire width, and frame design. Check the rack’s per-bike weight limit and e-bike compatibility before loading a lightweight eMTB.
Do lightweight eMTBs need more maintenance than regular mountain bikes?
They require the same basic suspension, drivetrain, brake, and bearing maintenance as other mountain bikes, plus periodic checks of the motor, battery, wiring, and software. Service requirements vary by drive system and manufacturer.
Can lightweight eMTB batteries be removed for charging?
It depends on the model. Some lightweight eMTBs use fixed integrated batteries, while others offer removable batteries or external range extenders. Check the specific bike if off-bike charging or battery swapping is important.
