Quoted message said:Now, I don't want to spend more than
150œ in the bike. Which kind of bike should I buy? To carry the
groceries, should I buy a set of panniers? I'll also need a rack,
right? Are racks compatible with any kind of bikes?
The best panniers for shopping (and most other things) are Ortlieb
classics. Unfortunately they're £75 a pair. Cheap panniers (£20) can be
had, but they're often [censored]. However, they will do the job and be a lot
cheaper. One of the worst things about the cheap panniers is that
they're fiddly to take on and off, but if you're leaving them on the bike
that's not a problem.
When buying a rear rack, get one with a 'dogleg'. This will stop the
cheaper panniers from flapping into the rear wheel.
As for the bike something without knobbly tyres, no suspension
(important) and mudguards is good.
It'll be impossible to get something both good and new for your budget -
'okay' bikes start at around £150, but £200 gets you something fit for
purpose. Getting one that already has 'guards and a rack saves you a
bit. Budget for a good D lock too.
Check out your local freecycle (google for it) group - you might be able
to stick a wanted notice up - that'd prolly get you a bike with 'guards
and a rack, plus a pair of panniers. Beware of second hand bikes thobut
- to replace the worn drivetrain (the chain, chainrings, rear
block/cassette usually need replacing) will often cost nearly as much as
a new bike!
