Alber e-Fix E35

Alber e-fix E35 – Add-On Power Drive for Manual Wheelchairs

Turn Your Everyday Manual Wheelchair into an Agile Powerchair in Seconds.

The Alber e-fix E35 bridges the gap between active manual mobility and motorised convenience. Designed for standard adult wheelchairs (with a user weight capacity up to 120 kg / 264 lbs), this compact conversion system replaces your standard rear wheels with motorised hubs – delivering effortless electric propulsion without taking away the portability, folding ability, or look of your custom manual frame.

Key Features & Benefits

• Effortless Conversion: Quick-release drive wheels click on and off with a single push of a pin. Convert back to pure manual push rim mode or disassemble for transport in less than a minute.

• Compact, Discreet In-Hub Motors: Brushless drive motors are integrated entirely inside the wheel hubs. No bulky external gearboxes or intrusive chassis modifications.

• Intuitive, Programmable Control Unit: A sharp, high-contrast 2.4″ colour display provides real-time battery status, speed, distance travelled, and customisable drive profiles (indoor agility vs. outdoor speed).

• Fold-and-Go Compatibility: Your wheelchair maintains its standard folding mechanism. The battery pack weighs just 2 kg (4.4 lbs) in lithium-ion format and unclips with one hand.

• Mobility App Integration: Pair via Bluetooth with the e-fix Mobility App to configure drive parameters, view real-time diagnostics, and remotely steer the chair into a corner or car boot using your smartphone.
