Results to date from the Ebike Monitoring Project 

In our second test phase, we have continued the testing we did for the E-Bike Report.  As we have collected more data, we have found a wider range of results than in our initial analysis for the November 2019 E-Bike report. We will continue to update this page as we collect more data.

Methodology for the analysis is explained on the FAQ page.

Cumulative average for all bikes tested to date 

Comparison to electric or gas powered car 

Typical high efficiency all electric car (2021 Chevy Bolt, similar to Kia Soul, Tesla 3 or S Long Range)  

Gas powered car - typical average car on the road currently

Results by e-bike type

Pedal assisted commuter e-bikes

Pedal assisted cargo e-bikes

Pedal assisted recumbent tricycle e-bikes: 

Pedelec mountain & fat tire e-bikes (mixed trail and city riding): 

Throttle only mode (little to no use of pedal assist) commuter e-bikes: 

We have done a very limited amount of electric scooter monitoring, finding similar results to the throttle only commuter bikes bike at just over 1000 MPGe over 9 miles of riding.

*MPGe = miles per gallon equivalent - an EPA metric based upon the energy contents of gasoline and electricity.  See the FAQ for details on how MPGe and CO2 are calculated.

More studies on e-bikes - how and why people ride them, their impacts and the effectiveness of incentive programs - can be found at the ClimateAction Center's E-bike Studies page.
