Hi, I've just had my new Cyclamatic 'safety checked' at the local bike shop in Crediton. They think the rattling noise it makes when ridden are the spokes on the back wheel. Is this a common problem with cyclamatics? Is it a long job to get them tightened?I see from other posts that squeaky front brakes are a common problem. My new bike squeaks loudly. Is there a good on-line bike spares sites whre I could purchase shimano calipers and brake pads mentioned. I know someone who might be able to fit them for me. Apart from these teething problems I'm really enjoying riding the bike. A friend who has an electric Giant gave it a test ride the other day and she said it felt the Cyclamatic felt more powerful on pedal assist. PJK
