Raleigh have a number of electric bikes on the market - though there offer will be developing now that they are part of a Dutch based group.
The entry level bikes are the Velo Trail X-Bar and Velo Trail Low-step.
These bikes have motors in the front wheel and 7 speed derailleur gears. The battery is mounted on the rear rack. They have 26 wheels and are fit to ride both on and off road. These bikes retail at £1,100.
All Raleigh electric bikes work with torque detectors that measure the effort you are putting in as a rider and then adds power in proportion. This means that if you are struggling up a hill, the bike will add to your effort.
The Velo-Cite is £100 more expensive than the Velo Trail. It has larger wheels (700c) and 7 speed internal gears. It is comes in X-bar version and low step version. The X-bar version comes in two sizes.
The next level up is the Dover model. This has a crank mounted motor and battery mounted behind the seat tube.
The Dover is fitted with a 3 speed internal hub gear system and built in lights and mudgaurds - a very practical and nice looking bike retailing at £1,700.
As with all of the Raleigh e-bikes these bikes have suspension forks and a two year warranty.
The top of the range for Raleigh is the Leeds model. This is similar to the Dover, but has more gears (7 speed internal hub) and a bigger battery giving a longer range.
Raleigh e-bikes should be maintained by registered maintainers who will note the work done on a centrally held database. This ensures that the bikes are properly maintained and give a trouble free service - a full service record will also help keep up the re-sale value of the bike if and when you decide to sell it.
