Puncture protection

[Merv]

Hi all, I've had to revert back to my trusty mountain bike temporarily until I can repair a rear puncture in my ebike (CE Deluxe). Due to past experiences with thorns from local hedgerows penetrating bike tyres I purchased tyre slime liners from Halfords for my mountain bike. Now either I've been lucky or they are working well.... had no punctures. I visited my local Halfords store earlier today but they don't stock liners for my tyre size (22x1.75) Talking to their cycle guy suggested cutting up worn out treadless tyres, and use them as liners!! I've noted elsewhere in the forums, liners have been favoured. So where can I obtain liners quickly and can they be fitted without the need to remove the rear wheel? Also this bike has an annoying squeal when applying the rear brake... I need to take a look into this and would appreciate advice on tackling the inspection / dismantle, as it seems likely I would have to remove the wheel.. in which case how do I go about it?_ The bike pulls up onto a stand which shares the same mounting point as the rear wheel spindle and drop arm for the pedal crank.
Cheers Merv

I don't know this bike personally Merv, so can't help with precise details.

Looking at it in photos, like many cheap Chinese shopper bikes it appears to use a band brake on the left of the motor. These squeal! Sorry, but it's a fact of life with them. You can introduce a drop of oil, they often have a tiny hole for that, but of course it lessens the braking quite a lot.

They work by pulling a steel wrap-around strip onto a wheel drum with pulls it more tight as it rotates, hence the braking effect. Of course, being steel on steel, it's bound to squeal, a bit like a car with all the linings worn off the brake shoes.

I fitted slime liners after many flint punctures on a little track that I use daily.
No punctures since(that's tempting fate isn't it).

I think that if you could get one side of the tyre off the rim and back on without removing the wheel then it would be possible to fit the liner. It would probably be quite fiddly though, so if you tackle it, give yourself plenty of time.

Thanks Richard, I'll try the Halfords liners for 24" wheels and fit those then. Thanks for your help merv

Thanks John, will give it a try.

Cheers, thanks again flecc. Crude braking method! I suppose you only get what you pay for, it seems quite a sturdy built bike I didn't pay a fortune for it secondhand.

Yes, these cheap bikes are usually quite strong and the motors seem to go on for ever, but unfortunately the Chinese seem to have an addiction to that simple but crude brake for cheap e-bikes.
