We set many goals when this charity began and one of them was to make riding a bike much easier for children missing upper limbs.
This is 8 months in the making .......
Many concepts were thrown around but the 2 that stuck out were to make bikes more stable to ride without leaning and being able to stop properly and safely.
Cups have been around for a while but most were just stationary and had little movement. We designed an ergonomic cup using Fusion 360 which narrows in the middle. This means that the majority of "little arms" can fit in with plenty of room while still having a narrow surface to push against to make the handlebars turn with a single size for a specific age group. Larger versions have also been modified for older children / teenagers.
The Cup is connected to a 360 degree ball joint meaning movement in any direction and gives more control to the user.
The second thing we wanted to concentrate on was stopping power. Having one hand means it is almost impossible to correctly use both brake levers and therefore reduces the ability to apply the brakes fully.
We managed to source an adapted brake lever which couples both brake lines together. This is installed by removing both the original brakes, taking the lines from the front and the back brakes and mounting them inside the dual lever placed on the side of a child's non affected arm. One hand will now easily give 100% of the bikes stopping power from 1 arm.
We bought the base bike at Halfords in Barnsley who kindly gave us a discount and are looking to help us more in the future.
This bike is being sent to a little guy called Kobi. Kobi has the special job of trialling the adapted bike to see how other children find and adapt to the changes.
All being well and with a few minor adjustment we will be fundraising throughout the end of 2018 and beyond to supply as many of these bikes to children who will benefit from one 100% FREE OF CHARGE.
The STL files for the cup will be available open source on the internet very soon. This means that the design can be printed by anyone in the world at no cost. We hope this design helps others help others!
We hope that these bikes will get limb different kids outdoors to meet new friends, give them a confident boost in their abilities and most importantly reduces falls and accidents when riding.
Thank you to everyone for their support with LimbBo. This is just a long line of projects we have lined up to help kids so stay tuned!
The long and stressful nights have all been worth it :)
