A BMW motorcycle is rebuilt so the user can roll onto it with the wheelchair and drive without having to transfer. A rod is attached to the wheelchair to anchor the chair to an attachment device on the motorcycle. The ramp is on the back and operates by remote control. The company specially adapted the gearshift to the user, who has impaired hand function. See also www.mobilityconquest.com. The person in the photo is not the user.
The company was founded by Alan Martin. He began to develop the motorcycle when his son became disabled. The motorcycle can be used with an electric wheelchair. The company is willing to discuss individual modifications.
