This is an assistive device designed to help a person with an upper limb difference to comfortably ride a bicycle. It was designed by members of eNable Lowell, an on-campus group at the University of Massachusetts Lowell that designs and distributes 3D printed assistive devices to people with limb differences.
Note: The handle pictured was for our first recipient. You may need to modify the size, length, and other aspects of the socket to provide a comfortable riding experience for the user.
Another Note: Print two of the "grips" in order to complete device assembly.
The handle bar attachment and socket should be printed with supports, and in PETG for added strength.
The grips need to be printed with a flexible filament such as a TPU filament or flexible PLA.
- Sand any rough edges and remove support material if used.
- Cut and apply polyurethane foam to inside of gauntlet.
- Remove pre-existing grips from bicycle if not already done so.
- Connect the socket to the handle bar attachment using 1 M5-0.8 x 50 mm bolt , placing a washer on both ends of the screw.
- Tighten to preference with the M5 nut
- Insert the M5-0.8 x 30mm bolt in the other hole, placing a washer on both ends of the screw
- Place one of the grips (printed in a flexible material) onto the handle bars. If hard, use isopropyl alochol in order to make it easier to slide on.
- Slide device onto the half grip that is on the bike.
- Slide the second grip onto the handle bar, pushing it snug up against the first one.
- Tighten the M5-0.8 x 30mm bolt to preference using an M5 nut.
