Good morning,
Sorry but I absolutely hate what you are describing.
I read what you wrote, thought about it for a while but it sounds to me that you plan to run a "life style" business/hobby not a charity.
Fault diagnosis would be free and if new parts were required, the person would be advised on what they needed to get to effect a repair.
charging a fiver an hour for its use.
£5 per hour sounds expensive if you are genuinely a charity especially as 2 or 3 visits may be required to fix up a beaten but recoverable bike, then the owner has to buy their own parts.
When they've sourced the parts, they could book a repair slot online and somebody would be on hand to advise them as they do the work themselves.
Assuming that this is possible as it assumes easy internet access, this is very business like not informal charity help to get your bike working like.
How will this work when wrong advice is given and the person has spent more than they can afford on a part, or the part was needed but it turns out that more parts and money needs to be spent to complete the job?
What happens when the next free slot is a week away? Or are you assuming enough volunteers being available to allow you to be open 5/6/7 days a week say 09:00 - 21:00
The attraction for the user will be the saving on specialist tools which they would otherwise have had to buy (freewheel tool, torque wrench, chain splitter etc.).
It doesn't take many visits and it would have been cheaper to have bought the tools, except a torque wrench but who uses one on a non CF bike?
For experienced cyclists of means, the workshop and tools would be available for free in exchange for either volunteering time or a decent donation.
How many people would this really apply to? Especially as you require an enhanced DBS check for volunteers and a decent donation is surely greater than £5 so will be close to the cost of the tool anyway.
genuinely unable to pay for spares or workshop time, assistance would be offered.
Isn't this is whole point of the charity anyway?
KIds under 16 would have to be accompanied by a responsible adult
That seems to rule out a big portion on those who would benefit.
.... and all volunteers would would have to satisfy a full working with children check.
Expect many volunteers to tell you that you are being unreasonable, quite possibly less politely, and you have just added a £40 per volunteer cost for an enhanced DBS check.
Overall it sounds worryingly like you would be using charitable status, volunteers and goodwill to be in competition with people who make a living in this business.
Bye
Ian
