Our special solutions for adaptive cycling

When it comes to mobility with unlimited comfort and enjoyment in spite of physical impairments, customized solutions can make all the difference. People with rheumatoid arthritis, stroke-related symptoms, thalidomide-induced limb defects, and various other physical and mental disabilities can experience independent mobility with HASE BIKES vehicles and our adaptive-cycling accessories.

  • Accessories

    HASE BIKES Seatback Extension

    The HASE BIKES Seatback Extension can be used for extending either the seat or the seatback by 2,75" (7 cm). More space - more comfort!
  • Accessories

    Special Pedals

    We designed our new Special Pedals in cooperation with Georg Busch from the company Ergodynamik Busch. They are much more adjustable to individual needs than other models: for starters, they fit an impressive range of shoe sizes, from US kids' 1/UK kids' 13 / EU 32 to US men's 16 /UK 15.5 / EU 52. And the angle to the direction of travel can also be adjusted over a very wide range. Once all adjustments have been made, the straps can be easily fastened and released with one hand. The foot is held comfortably and securely in the proper position.
  • Accessories

    Hand-crank Assembly PINO

    The sporty crank for tandemists with compromised leg function. The Handcrank Assembly for the PINO is height adjustable and can be folded forward for mounting and dismounting. Can be ordered with a new PINO (option) or as a conversion kit. Not compatible with the PINO PORTER.
  • Accessories

    Switchable Fixed/Free Hub

    With a fixed gear hub, the pedals remain in motion as long as the trike is moving. This option can be helpful for physiotherapy patients and people with physical limitations. When used on a trike that is being pulled as a trailer, the fixed hub keeps the pedals in motion (with a friction clutch). The new version can be switched from fixed gear to freewheel and back again with no tools.
  • Accessories


    If your arm needs a little support for steadiness, this comfortable armrest ensures a relaxed arm position.
  • Accessories

    One-sided Leg Support

    A solution for people with paralysis on one side of the body or a disability. The healthy leg pedals while the other is safely strapped into a comfortable support. Infinitely adjustable. Mounts behind the bottom bracket.
  • Accessories

    Single-hand Controls

    A single grip with all control elements! Using a special adapter, two brake levers can be mounted on one side. This allows the rider to shift gears and control both brake levers using a single Hand.
  • Accessories

    Holder for walking stick

    Just place the walking sticks or cane in the holder, secure them with the clamp, and hit the road. Multifunctional. Fits tubes 5/8"-21/3" (15-60 mm) in Diameter.
  • Accessories

    Harness System

    Our newly developed Harness System with integrated child-proof buckle guard is not only user-friendly, but also versatile: it can be used as a combined lap and shoulder restraint or as a 5-point harness with an additional strap between the legs. Even more comfort can be added with the optional pads.
  • Accessories

    Shoulder Pads

    The optional Shoulder Pads are available for use with the Harness System. They offer additional comfort and can be adjusted for riders of all sizes.
  • Accessories

    Handlebar Extensions

    The KETTWIESEL and LEPUS can be equipped with handlebar extensions of up to 31½" (80 cm) in length. This makes the trikes accessible for people with very short arms.
  • Accessories

    Coaster Brake

    When the legs are more mobile than the hands, the coaster brake ensures full braking power - with high tech: pedaling backwards transfers the leg power to a hydraulic disc brake.
  • Accessories

    Special Steering / Shoulder Steering Unit:

    Mobility for people with no arms or short arms. The width of the steering unit is fully adjustable. A coaster brake is used for stopping, and the Shimano Nexus automatic hub gears, for shifting.
  • Accessories

    Tow Bar

    Lame name, fine piece of equipment: with the Tow Bar, even standard bikes can be used as towing vehicles for the TRIKE - with a safety bonus: the integrated overrun brake works automatically. When the towing bike brakes, the TRIKE brakes.
  • Accessories

    Crank Shortener with angle compensation

    It may sound like something from a Monty Python sketch, but it’s actually an extremely useful ac- cessory: the Crank Shortener makes it possible to freely adjust the length of the crank arms, e.g. for riders with legs of different lengths. The new forged part not only looks nicer than the previous version but is also more robust and can even be properly aligned on offset crank arms.
  • Accessories

    Calf Support

    The Calf Support was redesigned for use with the new Special Pedals. Its unique and ingenious structure provides firm support for the leg but enables the ankle to flex naturally, allowing for a circular pedaling motion. This freedom of movement - made possible by an adjustable elastomer spring - is important because, when a joint is immobilized, the muscles atrophy.
  • Accessories

    Pendulum Pedal with angle compensation

    The Pendulum Pedal can help riders with severely limited mobility slowly gain flexibility and strength. The design of the Pendulum Pedal has been slightly updated, but the biggest change is the new hole. To be exact: a drilled hole. This hole can be used for reaching the adjustment screws of the Crank Short- ener, which saves time and hassle when adjusting the position.

HASE BIKES drops in on ‘t Mannetje

This video spotlights ‘t Mannetje, one of our dedicated dealers from the Netherlands. The bike shop in Haarlem (near Amsterdam) has several employees and offers a wide selection of bikes and trikes for adaptive mobility.

A double dose of iron

Nicholas Garwood is a 15-year-old South African who happens to have cerebral palsy with spasticity. And a dad whose favorite pastime is ­competing in triathlons – especially the Ironman – with his son on the PINO. We met with Team Garwood at Ironman South Africa 2014.

“We can do it!”

The Kaywald School for mentally and physically disabled children has been running a cycling club as a successful part of its curriculum for several years now. In 2015, a group of students and teachers set a particularly challenging goal for themselves: cycling over the Alps! We joined them for two days of their journey.

Making of:
TRIX – Trike it out!

Sometimes, moving forward means putting up your feed and leaning back in your seat. Sounds like a paradox, but is actually just a TRIX. A recumbent trike with a low center of gravity, the TRIX is so stable and agile that even riders with severe disabilities can master the controls – how cool it looks, you can see in the clip!

Making of:
PINO – Fun to the Power of 2.

There are at least two good reasons for a PINO: you and me. You´ve got the front row, I´ve got the overview and we´ve got a fun family adventure. How great that is, shows the clip.
