I’m thinking about getting a trailer for grocery shopping (doesn’t need to hold kids or pets and to be towed behind my ebike) and I’m after advice:

I see that there appears to be 2 main types of coupling … Seat post or nearside frame.

1. Can the frame mount be used with my existing thru axle, or would I need to get longer ones?

2. I currently have to change wheels when I swap from road to gravel riding; will a frame mount complicate this?

3. What is the benefits of seat post over frame and vice versa?

4. Are two wheeler trailers better than a single wheel for road use?

Any advice or info gratefully received.

Isn’t your qr bit part of

Isn’t your qr bit part of your axle though? Not sure how you would use that with yor existing through axle.

When I had a quick look at trailers, some gave you a longer qr skewer to accommodate the extra length which is also what you get with the thru axle replacement.

Might be worth a conversation with sjs cycles.

I’m not sure that makes sense

I’m not sure that makes sense to me.

Firstly, what Tom shows is that there is a hole that matches up to a QR lever and the towed item attaches to the post in some way. I’m assuming that the above picture of yours also assumes that the hole on the left is attached to the bike and the QR device is to attach to the trailer.

Without knowing your through axle design (because there have been many) what we are seeing now is a move towards standardised designs with a 4mm hex socket and they provide a QR style handle to plug in to it. The QR lever often does not work with a cam but simply is a means of rotating the srew in fitting, either with a hex socket or with a nurled interface. It’s unlikely that you can fit something inbetween the head of the through axle and the frame because they are engineered to fit the bike, and if you put something in the way, then the threaded end on the drive size isn’t going to be fully home.

The main issue you have is that with a through axle, you need a fitting that can take the strain of towing. Something clipped on the end isn’t going to work. The QR design works because it is clamped close onto the frame so there isn’t much leverage. With a through axle, you can’t just bolt something on the end because there is nothing to bolt to. I would have thought that to get something to work with a through axle, it is going to need a replacement axle to provide sufficient purchase for the trailer.

It seems, at some expense, these modified axles exist. See

I was looking at the below

I was looking at the below type of hitch as it seems to be compatible with QR axles – I’ve got QR levers on my thru axles.
(https://www.amazon.co.uk/Tiberham-Universal-Attachment-Replacement-Connector/dp/B07VW77NWH)

I guess with the connector that Tom shows, the trailer has a female part that the post slides in and is held in place with a locking pin.

Would that work with the type of attachment I’m looking at?

I’m trying to reduce the amount of hurdles that I might face so I have an easier time of it.

Thanks Tom.
Thanks Tom.
It was the rear view you posted that got me thinking again of a trailer.

My HOMCOM one came with this

My HOMCOM one came with this mount. The bit I’ve marked with the arrow attaches to the rear axle, and the trailer attaches to the other bit. My bike has quick-release wheels so not too sure about thru axles.

I got a frame mount trailer because I thought a seat post mount would limit what I could put on the bike’s rear rack.

Other advice – you may be able to find a cheap trailer 2nd-hand. Nextdoor / Facebook groups are probably the best place to look as it’s usually a “pick it up in person” deal.

There is a wizard that tells you what you need.

2 frame mount is normally axle mount ( so I hope we mean the same thing). The hitch fits onto the new axle and has a locknut. Once fixed on, you can remove the through axle as normal ( unless your bloody rack gets in the way !!!)
Unless your axle spec is identical, you will need 2 axles

3 I did hire a seat post one and did not like it. It seemed to spring back and forth and drag a lot. Must be incompatible with carbon post.
Lower to the ground axle would seem more stable and easier to manoeuvre due to ball and socket joint or cheapo big spring. Definitely less drag.

4 single one will be narrower if you need to go through a gate or anti motorbike gate.
2 wheels must be more stable.

I know captain badger and wtjs have a trailer and at least one of them has a single wheel yak.

I have a cheapo one same as tom_77:
“I’ve had my eBike for about a year, recently bought a trailer for it so I can do the weekly shop with it.

Bike is a Raleigh Motus, trailer is a HOMCOM cargo trailer.”
