Fat bike or Dually?

Postby MarcusT » 19 Jul 2017, 10:32am

I am shopping for a specialty bike. I want to use it to ride on river beds, with sand, loose gravel and rocks. Several bike shops have recommended the dual suspension 27.5+, but I keep getting drawn to the fatty. Watching videos online it seems to be what I am looking for.

Any input would be appreciated.

Can't say I've ridden many river beds, ( a fair few stream crossings ! ) but I do have a fatty ( Surly Pugs ) and what you do get with 4" tyres is plenty of grip and cushioning which also boosts confidence with technical riding ( The bike also rides really well when loaded up ) The only downside to the fat bike I'd say is riding on the road and forest road climbs where the rotating weight and drag of the tyres become more noticeable. I've not had much experience of 27.5" + It may well be the better all round mtb option - In a full suspension format it may well be very good on technical terrain and perform well on river beds, though regular maintenance / servicing will be needed as with all full suspension bikes compared to a rigid machine.

I would go for the fatty. I have a 27.5+ hardtail and a Pugsley with quite a few miles on both. Given your particular requirement, I think the deciding factor will be the considerably better grip afforded by the larger footprint of a 4 or 5 inch tyre.

Fatties are more fun!

Better grip, more fun, you know what to do :)

So, I tried both bikes. A friend let me try his dually with 27.5. It is a nice bike. nimble, comfortable and easy to handle, but the fat bike is exactly what I am looking for. It can handle the sand, soft gravel, lateral slopes, where the 2.4" was bogged down or had less traction. The fatty rolled over rocks that I would normally have avoided.
The downsides of the fatty? Uphill SUCKS!!! It was like pushing a wheel barrel uphill. That and road handling was a little sleepy.
The dually is great for single track, but the fatty is great for no track.

Thanks for the input.

I disagree with Marcus on one point, I don't find an issue riding up hills on my Pugsley. I have 10+ bikes mostly SS or fixed so it's easy to compare. The Fat bike is the comfiest I own, I did 3 good days of riding last weekend, including some interesting hills....try different bikes, go in with an open mind and enjoy.....
