A new group of companies is aiming to deliver a small engine in as little as three to four years for a range of different electric bikes.
While the industry is still nascent, small engines are a way to help keep costs down, said Jeff Biesek, vice president of engineering at Fumi, a maker of small-diameter combustion engine pods.
The company’s new electric bike engine is the first to use a lightweight, low-power, low fuel system.
The engine is powered by a small electric motor with a high-performance, aluminum casing that powers a single electric motor that has a top speed of 200 mph (370 km/h).
It uses a lithium-ion battery pack that can be recharged by plugging in to a power grid, which allows the engine to run on batteries for about three to five years.
Fumi is the only company making the electric bike, and the company has sold more than 200,000 units since its debut last year.
The engine is not the only way that Fumi and its peers are trying to develop the electric bicycle market.
A group of bike makers, including Fumi as well as several other companies, are working on new engines.
Some of those bikes are powered by small, lightweight engines that can also run on hybrid electric motors, batteries, or other alternative energy sources.
The electric bike industry is also seeing a surge in interest from larger companies that are building and selling electric vehicles, such as Honda, Mitsubishi and Suzuki.
Honda has just announced plans to build and sell the first of those vehicles to the U.S. market in 2019.
Suzuki is also building a battery-electric motorcycle that it expects to be in service by 2021.
The growth of the electric motorcycle market has attracted interest from large companies that can offer the benefits of electric bikes, such the Harley-Davidson Company, a Japanese motorcycle manufacturer.
In March, the company said it had sold more electric motorcycles in the U, U.K. and Canada than any other manufacturer.
The interest in electric bikes has led Harley-Davidsons to expand the business, opening a factory in Japan in 2016 and hiring more than 150 employees.
It now employs more than 1,100 people.
