Yes Its a Modified Twenty, Anyone that has owned or ridden a Raleigh Twenty will quickly realise that it is not the greatest ride, that is until it has been modified in some way. The basic H frame design is in my opinion one of the greatest bicycle designs, OK may not be the strongest or the safest but still a pleasure to ride,the caliper brakes leave a lot to be desired when it comes to stopping, especially in the wet.And yes there are quite a few other things that many people modify to improve a great little bike. Not forgetting the fact that these little bikes are basically a Child's bicycle, 20 Inch wheels with three speed hubs, low seat, low handlebars, all these things need to be modified for Adults, This is where the fun begins has most of these bicycles are used and ridden by Adults and Larger than normal children.
Anyway Here are some of the specs of the bicycle I built has a copy of the Raleigh Twenty.
The head tube on the Raleigh is 185 mm long mine is 100 mm long to take a front suspension fork with a Disk brake, I lengthened the head tube to seat post tube from 490 mm to 575 mm this is to allow more clearance from knees to handle bars, the seat tube on the Raleigh is 405 mm mine is actually reduced to 370 mm the reason for this is that I have moved the seat post to the rear more, this makes for easier pedaling for people with old stiff knees (mainly me) The wheel axle centers are the only thing that remain the same at 1000 mm.
The handle bar goose neck has been lengthened, and I shall be fitting a luggage rack and drink bottle holder soon.
