If those front brakes are "high performance" I'd hate to see the "standard" performance ones  ;D

...don't forget, under hard use (i.e. downhill  ;D) ,they have been known to melt the standard Sinclair plastic front wheel  :o

Better brakes would only make this worse , so changing to a steel front wheel is possibly the best "mod" you could make.

I'll second that.  When going down a hill at about 25 mph, you soon apply the brakes.   Then comes the smell of burning rubber, then a buckled wheel, then 'BANG'!  The inner tube has burst.   :o

Steel wheel all the way!!

Where do you find a metal front replacement wheel, and are there replacement brake blocks for the front?

We tend to use steel wheels of a kiddies bike , although they are known as 12" in size, they are actually only about 8" ! Go by the tyre size.

Standard bicycle brake blocks as fitted to any eighties style caliper brakes (like those for Choppers,Grifters etc ) do the job.

Did you all just buy kiddies bikes and cut them up? That seems to be the only way I can find such a wheel, but it just seems wrong to do something like that. There must be a supply of just the wheels somewhere, right?

Bit of both really, a local independent bike dealer was happy to sell us wheels at about £15 whereas the bigger guys such as Halfords tend to break new unused bikes for spares (for warranty claimes etc) as it works out cheaper for them to do so. If you're lucky they sometimes sell you the left overs.

I know the front brake is pretty poor, but the original brake blocks lasted longer than the replacement ones I fitted, really shocked when I see how worn they were after only a short time.

Ah, the brake blocks are high performance - that's why they melt the wheel!!  ;D

Not if you have a steel front wheel  ;)

If you start to melt that then you've already got your hands full with a host of other problems   ;D :D

Strangely I had no prior knowledge or fantasy of the combination of Sinclair C5 and the smell off burning rubber!  ???

12"? I thought the front wheel was 16" (haven't measured it and I have no intuitive sense for lengths, diameters etc). What are the actual wheel sizes I'm after then, including widths?

Thanks

Thanks Chas. Are there not different widths though? I thought I had to specify two dimensions eg 16x1.75".
