Custom Adaptive Bicycles: Comfort and Mobility Tailored to You

For those for whom cycling isn’t a given – due to physical limitations, injury, or changing mobility – a custom adaptive bicycle can be a life-changer. But what many people don’t realize is that an adapted bike doesn’t have to look medical or bulky. Sometimes, small modifications can make a world of difference. In this blog, we explain how custom adjustments improve comfort, safety, and enjoyment, and how we at Astonic build bikes that truly suit your body and lifestyle.

An adaptive bicycle is a bike that differs from standard models in order to better suit the needs of the user. This can range from minor ergonomic tweaks to fully customized frames. The goal: to make cycling possible again for everyone – safely, comfortably, and pain-free.

You don’t need a medical diagnosis to benefit from an adaptive bike. Consider:

• Ergonomic saddle – for those with saddle pain, back problems, or who want extra support

• Raised or custom handlebars – to relieve neck and shoulder strain

• Custom grips – for better hold or less wrist pressure

• Suspension seat post – to absorb shocks and increase comfort

• Shortened crank arms – for those with unequal leg lengths or limited knee mobility

At Astonic, we tailor these adjustments to your body, so you experience maximum comfort and control during every ride. Also ideal for those with arthritis or rheumatism.

Sometimes a standard frame just isn’t enough. That’s when we create:

• Low step-through frames – for riders with reduced mobility or balance issues

• Compact frames – for shorter cyclists or those with limited range of motion

• Sky High frames – specially made for tall people (from 185 cm and up)

• Asymmetrical frames – for riders whose bodies don’t move symmetrically

These modifications ensure that you can ride safely, steadily, and comfortably – without needing to "compensate" with your body.

Poor posture on a bike can cause pain in your back, shoulders, neck, wrists, or knees. That’s why at Astonic, we focus intensely on proper geometry and fitting. We consider:

• Seat angle and handlebar reach

• Knee alignment with the crankset

• Seat and handlebar height

• Balance and weight distribution

The result? A bike that supports your body rather than stressing it. An ergonomic e-bike that’s ideal for daily use – even with physical limitations.

• People with physical complaints (back, knees, shoulders, balance)

• Seniors who want to ride confidently and safely

• Individuals in rehabilitation or with chronic conditions such as MS or Parkinson’s

• People with asymmetry, prosthetics, or specific physical limitations

• Cyclists looking for pain-free, comfortable riding

• Anyone seeking an electric bike with a low step-through design

Every Astonic is handmade in the Netherlands. No adjustment is too small or too big. We believe everyone deserves a bike that fits.
