This place isn't what it once was. Nobody has said it yet, so I will.
For that money, just go fixed and you won't have to worry about the quality of gears and associated components
I think i will stick with a hybrid as i like coasting and have quite a few hills to go over
thanks
And if you go fixed the belt drive is out so you still need to change chains (and lubricate them). Although you will get so strong riding your fixed over the hills that you won't even notice the extra resistance of a worn out, clagged up chain
Having read the other posts I would add a couple of caveats:
1. I notice mention of Clarks hydraulic disc brakes. Their cable discs are not as good as a cheap V-brake, I wouldn't expect the performance of the hydraulic ones to be significantly better. They are very cheap!
2. Hub gears will go a long time without maintenance. This does not mean that they are maintenance free or that they will not be better, smoother and more reliable with regular lubrication (6-12 month intervals depending on mileage and riding conditions). They are very tolerant of chain wear though. The net is full of horror stories about unmaintained gear hubs that have suffered from water ingress. Just saying! I like them but best keep your ideas open
The cheapest way to get a bike is to hang around knowledgeable people who like to change their kit (perhaps join a club), learn a bit about how it all goes together and, above all, NEVER say no to anything that's being offered free. Unfortunately this also gets you a garage full of unusable junk DAHIKT
My daughter was looking for a bike in your price range to take a child seat (not for commuting though) and we have given up on the search - I'm sending her one of mine from France! Good luck with your hunting!
