Electric Push Trailer

Yes, you can certainly get 16" rims with 36 holes.

For instance: 36h Sun CR18 16 x 1 3/8 (349) silver alloy rim wit

thx...
wow.. i hope there is somewhere a cheaper source...
the rim alone costs more than the whole trailer sofar !!!

1.) the trailer does not need to carry more than 30kg.. so no ultra-strong rims are needed
2.) the torque from the motor will also be limited (not that much grip on the ground with light trailer) -> so no ultra-strong rim is needed

Alesa make a 16" (349 or 305) rim with 36 holes - that should be much cheaper.

It seems this idea may be re-kindled.
With the expected arrival of my new LiFePO4 battery I will have 3 12-volt batteries looking for a new home.
At the moment they may either go as spares for my campervan (for my solar panels) or be used in a push trailer project - can't decide.
I was hoping to get a spare battery box and make up a second battery for my ebike, but I have been informed that my battery box is no longer available, so had to scrap that idea

How's your push trailer going?

Hi I've got one of those trailers and use it to take house-hold rubbish to the skip. Part of the run is downhill (not dragging laden uphill if if can avoid it!) Note the pivot. I find as soon as the weight of the trailer gets out of line on a curve there is a distinct push at the rear as the thrust goes off centreline and the trailer tries to steer from the rear.. If you have power how are you going to keep the thrust in line, -lock out the pivot?

This is unknown territory for me, as I have never had a bicycle trailer.
flecc has already mentioned there may be a side-ways thrust from the trailer.
If locking out the pivot is necessary to stop the trailer taking control then I may have to do that.
All a bit "up in the air" untill I see and try the trailer out.
Thanks for the warning though

Work-shifts and plenty of heavy rain have kept me from fitting and testing the Mule trailer until today.
Before going anywhere I had to attach it to the bike.
The trailer is supposed to fit onto the wheel nut on the left hand side of the back wheel but that would have meant disturbing the power cables going into the back wheel - no-way was I going to mess that up.
So I made a bracket (from a part off an old trailer tent) and bolted it to the frame.
I was then able to bolt the trailer pivot to the bracket, leaving the wheel undisturbed.

I’ve just got to remember the trailer makes the bike set-up very wide

It's great though
