Bicycle Doctor - faqs

How do I know what size bike to buy ?

Touring / race bike with a crossbar
You need to be able to stand astride the crossbar/toptube with an inch clearance between you and the toptube.
Mountain bike
You need 3 or 4 inches clearance between you and the toptube.
Hybrid cycle
You need about 2 inches clearance between you and the toptube.
Open frame
This is a bit different as there is no toptube as such!
What we ensure here, is that the rider has a comfortable position whereby they can reach the handlebars without stretching unduly
