Newton on eBay

Hand Built Lightweight Racing/Touring Trike.

Newton trike on eBay

 "Hand Built Lightweight Racing/Touring Trike.

I have for sale an almost mint condition tourning  C21 touring trike by Roman Road Cycles.

The C21 uses a purpose-built tricycle frame, which has been designed to meet a variety of uses.  The frame is mostly built from Reynolds or Columbus tube, and construction is by bronze welding.  The absence of the traditional top tube makes the machine easier to mount, which is especially important to those with partial disability, while the use of a specially modified large-bore tube gives ample rigidity.  The C21 shares with the Newton conversion the "Tadpole" Kendrick-style layout with centre rear wheel drive, which allows the use of almost any conventional bicycle gear set and gives unrivalled traction as the rider's weight is directly over the driven wheel.  It also has the same steering arrangement which gives excellent stability and good handling. 

The frame is made with a fixed seat tube, and head tube angles of around 72° - the head tube isn't, in fact, a head tube but it's in the same place as a bicycle head tube would be from the rider's viewpoint.  

Equipment can be specified for various cycling activities, the one shown above is a fairly small frame set up as a light touring machine.  The frame is obviously heavier than a bicycle, but the overall weight is not excessive with lightweight wheels, tyres and equipment.  The machine can be specified with almost any normal cycle equipment.  Standard front brakes are mechanical discs on Hope hubs, which are fitted with our own design of 20mm quick-release axles; this makes it much easier to get the machine into a car.   

 Prices depend  very much on equipment specified, but start at about £1750 for a good but not too expensive setup, using mostly mid-range equipment.  We don't see the point in having a custom-built frame and fitting cheap parts to it!

8 gear rear touring  block

About 4yrs ago, when I realised I could no longer ride a 2 wheeler,  I had the frame, wheels with discs built for me, by Roman Road Cycles,  and put the rest together, to suit my needs. It has a touring rear block, with a campag twin chainset, giving a good spread of gears.
I have now reached the stage where I can no longer get the use out of the machine because of my disability. Hence the sale."
