*Ride Time Calculation: Based on an average power consumption of 210W.
Note: Comparison tags (Green/Blue) calculate the advantage relative to the lowest-spec model in each category. Green represents the best-in-class, Blue represents intermediate. Optibike "TruePower" represents sustained continuous output. Rotwild price is an estimate based on European MSRP.

Motor Output & Torque

Optibike G2 Loki
750W continuous output (TRUE POWER™)
190 Nm torque

Specialized Turbo Levo 4
650W peak output
111 Nm torque

DJI Avinox Motor Platform
950W peak output
105 Nm torque

Practical note: Torque influences steep climbing performance and sustained technical riding. Higher torque can improve climbing leverage and reduce fatigue during long ascents, especially on loose or technical terrain.


Continuous vs Peak Power

Peak power reflects short bursts. Continuous output is more representative of sustained performance on long climbs.

The G2 Loki emphasizes continuous output (750W). Many competing systems emphasize peak power figures. For extended climbing and technical terrain, continuous output can be a more relevant metric than brief peak bursts.


Battery Capacity

G2 Loki: 1440Wh battery

Turbo Levo 4: 840Wh battery

Avinox-equipped bikes: typically 600–800Wh depending on brand

Practical note: Battery capacity influences ride duration and total elevation gain potential. The Loki’s 1440Wh system provides substantially higher energy capacity than many mainstream e-MTB systems. Actual range varies with rider input, terrain, assist level, and conditions.


Suspension Travel

G2 Loki: 170mm front / 170mm rear

Turbo Levo 4: ~150–160mm (model dependent)

Avinox-equipped bikes: typically ~150–160mm

The Loki sits closer to enduro-level travel, which may appeal to riders seeking additional capability in rough terrain.


Drivetrain Longevity

Rohloff 14-Speed Hub vs 12-Speed Derailleur Systems

Drivetrain service life is an important ownership consideration for high-torque mid-drive e-MTBs.

Typical 12-Speed Derailleur Systems (Shimano / SRAM)

Modern e-MTBs commonly use narrow 12-speed chains and wide-range cassettes. Based on widely reported rider experience:

  • Chain replacement is commonly required around 500–1,000 miles
  • Under aggressive riding and high torque, wear may begin around 400–800 miles
  • With careful cleaning and lubrication, some chains may reach 1,200–1,700 miles
  • Cassette replacement often follows after multiple worn chains

High motor torque combined with narrow chain profiles and cross-chain angles contributes to faster wear compared to non-electric bikes. Service intervals vary widely depending on terrain, riding style, and maintenance.

Optibike G2 Loki – Rohloff 14-Speed Hub

The Loki uses a Rohloff internally geared hub featuring:

  • Straight chain line
  • Hardened steel sprockets
  • No lateral derailleur movement
  • Sealed internal gear system

Typical Rohloff user experience shows:

  • Chain life commonly in the 3,000–5,000+ mile range
  • Reversible sprockets for extended service life
  • Consistent performance under sustained torque

Because torque is transmitted through a straight chain line and internal gear system, wear rates are typically reduced compared to derailleur-based systems.


Which Rider Benefits Most from Loki Features?

Riders who climb steep, technical terrain

Higher torque output may help on sustained climbs and technical ascents, especially where traction and controlled power delivery matter.

Riders seeking extended ride duration

The 1440Wh battery is suited for riders prioritizing longer ride time and higher total elevation gain potential.

Riders interested in reduced drivetrain maintenance

The Rohloff system may appeal to riders who prefer longer service intervals and consistent performance under high torque.

Riders who value custom build configuration

Each Loki is built to order in Colorado, allowing direct configuration for terrain, fit, and component preferences.

Riders who prioritize capability and durability over weight minimization

Some e-MTB platforms emphasize reduced system weight and smaller batteries. Loki prioritizes capability and durability, including:

  • 190 Nm torque output
  • 1440Wh battery capacity
  • 170mm suspension travel
  • Rohloff internally geared drivetrain
  • Structural design intended to manage sustained high loads

For riders who regularly encounter demanding terrain, extended climbs, or long ride durations, these attributes may offer practical advantages.
