Knowle West-based cycling engineering company Revolutionworks Ltd has just launched a revolutionary new accessory  – to turn a bicycle into an E-bike.

The Revos is an innovative E-Bike battery kit that can be fitted to virtually any bicycle and provide electric power assistance up to 15.5 miles an hour.

The initial concept was the idea of motor engineer and Director Hugo Palmer. Back in 2011 he built the first prototype using a 3D printer and a cheap battery motor and was surprised to find it worked well. Since then, much work has been done to refine the final product.

A successful Kickstarter Funding Appeal back in 2018 enabled the Revolutionworks team to put The Revos into production – and they are currently in the process of shipping the first batch out to those who pledged to the Kickstarter.

Some 90% of the unit is built and assembled in Filwood Green Business Park – with only the main battery component manufactured by a third-party company.

Co-director Mark Palmer says they decided to pick the Business Park as the desired location for the company, because “the building is sustainable as is our product and overall, it’s a really nice place to be.”

He explains: “Our aim is to become an engineering company and the building will allow us to expand our work here.”

The product has been well received and is already selling through their website which means the company saves on costs.

Mark says: “Eventually we would like to sell through cycle stores as it will be great publicity for us, and people will be able to try out The Revos in other parts of the country.”

As well as commuters and cycle couriers, the team believe the power assistance of the E-bike battery kit will also be a great product to encourage older people to get out and cycle more.

The Revos has also impressed many of the popular cycling websites – garnering highly favourable reviews from the likes of and
