…commuting. Needs to be £1k or just less for Cyclescheme.

I’m also doing a 220 mile 12000m climb charity ride over 2 days later this year. Fat bike must be suitable (do they do 4″ slicks?)

do they do 4″ slicks?

Yes. http://surlybikes.com/parts/wheels/black_floyd

Go second-hand and budget for a light wheelset, there’s a set of Hugo’s and husker du’s for sale on here.

It’ll be on Cyclescheme, so need new and max £1k rrp.

Apache Fatty Slick

But whatever you do, don’t check the price!

Strewth, I’ve paid less for tyres on the ZX6-R

Jumbo Jims roll decently on tarmac, price is on the increase though.

I’ve not tried them, but Specialized Fast Trak Fats are supposed to roll quite well and can be had for less than 50 squids.

With the price hikes, you might struggle to find a sub £1k fat bike through CycleScheme, you can currently buy a Voodoo Wazoo for £400 before BC discount and vouchers bought through your employer at a discount.

So plenty of tyre ideas, but what bike?

genesis caribou ?

On one do fat bike road tyres. Not stupidly expensive.

Go Outdoors do c2w iirc.

As above, googlefu suggests Go Outdoors do CycleScheme, making the Calibre Dune a great option. Upgrade the brakes to hydraulics and replace the tyres, happy days.

But i suspect it will cost more than the Wazoo, potentially ~£325 before buying tyres, if you have not already committed to using a CycleScheme voucher.
