Lasher Sport is an amazing company. If you use a wheelchair and want to live life without limitations, then you need to look into this company. The owner, Bill Lasher, is a great guy to work with, and has helped me out tremendously with getting set up with the Lasher ATH. About 25 miles of my bike tour will be on a dirt road. This is the only hand cycle on the market that will cruise on the road, and also tackle the dirt without an issue. Just take a peak at some of the videos and you will see why this is the most hardcore hand cycle one can get their hands on.
