e-fix E25 and E26 electrical add-on drives combine the benefits of both power and manual wheelchairs. With a range of more than 18 miles on a single battery charge and, with the E26, up to 25 stone user weight limit, e-fix is easily programmed to optimise driving performance and can be operated without full hand functionality. Most current manual wheelchairs can be retrofitted with e-fix, so you can continue to use a wheelchair that has been adjusted to suit you.
