looks good, price seems good until you realise it doesnt come with the rear wheels and pins, ok if your good at sorting wheels out yourself but my last attempt seemed to be fine until i lost a rear wheel going over the threshold of my friends door, if it hadnt been for the quick reactions of my assistance dog i'd have gone over backwards off the side of the ramp, so i for one wont be adjusting my own pins again!!

Hi wheelywendy,
thanks for your comments regarding supplying the wheelchair with wheels.
It was a tricky decision, we could supply cheap wheels to keep the price down but it would spoil the design of the product. If we supplied top end wheels then the price would be far too high & negate our efforts to produce an affordable wheelchair with so many features.

Hi Nordigo.
just a quick response to your initial post asking for input & suggestions.
Would you consider a variable gear system whereby the start of the stroke is in a low ratio & the gearing gets higher as you reach the end of the stroke. This will help when starting from a standstill & when cruising a higher gear will be more appropriate.
So; if ascending a slope then shorter pulls at the beginning will have easier effort.
When already moving then shorter pulls at the top end of the stroke will give a higher speed.
The gearing could then be set to suit the individual depending where the ratio starts.
Hope this helps with your development.
