The 2,500 watt Optibike e-bike mid motor delivers insane power

Colorado-based e-bike company Optibike has a new high-powered e-motor that it says can outperform any other e-bike motor in its weight class.

The engine is called the Optibike Powerstorm MBBor motorized pedal.

Like many other mid-drive motors, it is mounted where a typical bottom bracket is on a bicycle, right where the pedal cranks meet the frame.

The 4 kg (8.8 pound) motor interprets the rider’s pedal input and provides significantly more assistance to help riders start and navigate tough off-road obstacles.

In this case, the Optibike MBB claims a peak power of 2,500 watts, or around 3.3 horsepower. Even the continuous power rating of 1.75 kW or 2.3 horsepower is industry leading in the e-bike market.

Perhaps more important than just raw power, the motor also claims to prevent overheating issues. The company claims it can maintain a continuous power draw of 1,750 watts while climbing steep hills in hot weather without overheating.

The new Powerstorm has the highest power-to-weight and volume ratio of any e-bike mid-drive motor in the world. The compact and lightweight design gives e-bikes better handling and larger batteries.

Larger batteries seem about right, as you’d want some serious battery capacity to power that power-hungry motor.

For example, the battery of the R22 e-bike from Optibike measures 3.26 kWh. That’s about 5 times more battery capacity than on an average e-bike.

Every MBB is assembled locally at Optibike’s Colorado factory, where the housing, internals and gears are machined from solid 6061 aluminum. which increases the overall resistance.

As Optibike founder and CEO Jim Turner explained:

Our new Powerstorm MBB represents the culmination of over 25 years of experience in e-bike design and shows that American creativity is alive and well.

Bikes like the Optibike R22 tame the motor’s 190Nm torque with a Rohloff Speed ​​500 internally geared hub with 14 gear ratios. At top speed, the bike and motor combo would deliver a top speed of 36 mph (58 km/h), making the R22 an all-terrain e-bike only as far as US laws are concerned.


Electric motors in US-market e-bikes have often played fast and loose with regulatory concerns, sometimes well over the allowed maximum of 750 watts.

In the case of motors like the Optibike MBB, the all-terrain designation means it doesn’t have to comply with the 750-watt limit.

In many cases, e-bikes with high-powered motors are equipped with limiters that allow riders to reduce power to legal limits for road use.

Other e-bikes have crossed into moped territory and even offered VINs with Manufacturers Certificates of Origin (MCOs) that allow riders to register the bikes as mopeds or motorcycles with their local DMV.

Most riders prefer to maintain e-bike status with legal power limits to avoid the registration, license and insurance hassles that come with mopeds and motorcycles.

Would you ride a high-powered e-bike with several kilowatts of power on tap? Or are you satisfied with street-legal e-bike motors? Let’s hear your thoughts in the comments section below!
