How big a car do you have?
A four bike rack for most cars will exceed your nose weight on the tow ball- that said so does 3 on mine and it drives fine

Pendle and plenty of others do them

Ease of fighting is a good thing to look at as they are bulky as is one that tilts so you can get in the boot

I would alos just geta four rackand just use three when you only needed three rather than try and fit another one on

I had a 2 plus one type one and the one bit needed some fettling to work properly.

Mine is old so I cannot really recomend a current model

We havw a Thule one, carries 4 bikes most of the time, including trips to the Alps

I bought a Mottez 4 bike carrier and it attaches quickly but I use the ‘U’ bolt to go round the tow-bar neck aswell (Just in case?)
Very happy with it as its very secure.
It will take a load of 80kgs (20kg a bike) and weighs 25kg , but the nose weight of my car (VW Touran) is marked as 75kg…
So… I made sure all 4 bikes weigh less than 50kgs together.

I have this baby:

Altera STRADA DL 3 to 4 Bike Carrier

Don’t have anything to compare it with, but it’s been pretty much perfect in the year or so that we’ve had it (including a few weeks of travelling all over the country). Light enough for getting in and out of the shed and mounting on my own. Can be fitted (including the bikes) in a few minutes. Bikes are held securely with no rubbing. Can be slid out of the way to get access to the rear door (Subaru Forrester) very easily. What more can you ask really?

Can’t comment on the 4th bike attachment though as it’s still in its box.

we have the same one as roverpig.

2 hardtails (12+14Kg), 2 kids bikes (c.10Kg) and a kids trailer (11Kg)

so 47Kg.

We lose the trailer this year, but the kids bikes go up a size as well. And my bike is quite light. 4x AM bikes is a fair heft.

the +1 fitting we use for the trailer ATM. Next year it will be for the smallest bike to keep the moment down.

Aistoncyclesracks.co.uk like the pendle design but much better in everyway and cheaper. I’ve had pendle, thule and aiston before going to vans and would now only use the aiston.

I recently bought the Halfords 4 bike carrier for £180. It weighs 15kg so can carry 4 * 15kg bikes to remain within my car’s 75kg limit.

My only criticism of it is that it requires 3 straps to secure each bike and threading each of these through it’s buckle takes a bit of time. I might try to get some alternative straps which are quicker to secure.

Overall though, good value for money.

Friend has the Pendle, but tbh on a Defender towbar you could probably get away with 8 bikes.
