Good machine, if a bit heavy

I have had this bike now for 5 years, and done considerable mileage. It has never let me down, but is very heavy to peddle if you run the battery flat - so don't do it! I am looking for a supplier to give it a good service after this time - nothing serious, but a bit of attention!
Altogether I am very pleased with the bike, and it is the envy of the neighbours! It also irritates the local lycra fans who I can keep up with effortlessly.
