The history of Steering Developments and the SD Motion range

At Steering Developments Ltd (SDL) we’re proud to have been delivering impeccable customer service and life-enhancing products and vehicles for over 4 decades.

1981

Steering Developments begins trading

Steering Developments Ltd was established in 1981, when a group of 7 engineers grouped resources and knowledge to set up the company now known as SDL. That was 4 decades ago, and Steering Developments Ltd has been going strong ever since.

1999

SDL becomes UK Manufacturer of Yamaha's power add-on devices

In 1999 we flew to Yamaha HQ in Japan to learn more about their power add-on range for manual wheelchairs. We were so impressed with these kits we brought them over to the UK and became official UK manufacturer of these systems.

This year also marked the introduction of the Li-ion battery, which offers twice the range of the Ni-MH battery.

2023

SD Motion Trike launch

In 2021 we were contacted by a Mountain Trike user, who requested we fit our SD Motion joystick system to their trike frame. We tried, it worked, and then great things followed!

We then partnered up with Mountain Trike to build the SD Motion Trike which we launched at Naidex in March 2023.

2025

Launch of upgraded SD Motion Drive

In March 2025 we were joined at Naidex by a rep from Yamaha to launch the brand new SD Motion Drive system. The upgraded joystick system now offers improved performance with more torque, increased load capacity, and the ability to manage 10 degree cambers. Aesthetically, the new system comes with black tyres, hubs and spokes as standard, as well as LCD screens on the joystick and attendant controller. The li-ion battery is lighter, the battery bag has an improved design, and there is an option of electronic anti-tippers for improved safety.
