I'm still amazed

A set up like this: http://www.whike.com/en/ looks like a lot of fun, not that I would expect it to sail up a hill.
Numbnuts and I use sails on our kayaks, even though he made his own, where I just bought one.

Coo, I could see one of those working on Romney Marsh!

Just wondering as I struggle uphills has anyone had experience with power trailers which can attach to a bent or trike[ e assist mono trailer}

We have played with electric bullies , they work , but on a trike they need to be dual wheeled trailers as the sideways forces will either destroy the rear of the trike or the trailer , Ideally two wheel drive with freewheels giving a "differential" effect on turning .rather than using an e-hub on the nearside
Using a jackshaft to drive the two rear wheels a 5 speed freewheel could also be used thus having a true geared motor that could push you and a loaded trailer up hill at 8 mph without much human effort.
After the twisting moment ,the main problem is the coupling between the trike and trailer , The electrical connector being waterproof and durable enough to last several connects and undo's before the cable breaks or the connectors fail , Lithium / lipos batteries work better to keep the weight lower and allow a payload to be carried
Like e-bikes you should consider cut-off brakes and a throttle and a pedelec sensor on the trike all these need to go back to the trailer where the controller is

As for the wind power , Still early days and gusts could be a problem

Did someone mention trailer........

Cars pass this with a wide berth , we use it for model flying as well as camping and shopping . its 41" long 24" wide and 12" high fitted with 22" QR wheelchair wheels to store it easier , non motorized as the e-trike has enough power on its own .
The sides are made from uPVC boarding with a ply base and pink tubular bed iron for the base frame .
...

UK law states that it should have red triangles and a rear light fitted , BUT does not say you need a front light !!!!!

Is that what @starhawk is talking about upthread?
.

No, I am talking about an e-assist trike i.e. a trike with an e-bike kit mounted

 

[voyager]

We tried the powered trailer concept but settled for a two wheel box trailer on the e-trike as it was " silly " to have fitted all the necessary bits on the trike
and leave the motor and battery at home when the trailer was not in use .

Now, if the trailer were only carrying the batteries … lo-o-o-ng rides would be in the offing !

That's just given me an idea for what to use for the sides of my trailer (a kiddy trailer I've had for years but the nylon has succumbed to UV) when I rebuild it

Only downside is that it comes in 5 metre lengths but you can get nice corner sections to cover the edges
I have used it for covering some wooden garage doors and it does stand up to UV ( sunshine )
Seal the parts with silicon or super glue will stick it together and a few dome headed bolts .

[QUOTE 3361755, member: 9609"]or some sort of energy recovery system that would charge the batteries on the downhill sections. (the use of the brake kicks in the generator)[/QUOTE]

Lifepo4 and lithium / lipos dont like regenerative charging but SLA's will cope but fit solar panels on the top of the trailer and .................

I have 2 identical batteries for the red trike (both 37v 9 ah ) and can carry the spare in the pannier if needed and I get an extended range of 40 miles with little effort , I have just got 3 Lifepo4 batteries all 37v 10ah that I havent decided what to do with them YET...

 

[Scoosh]

@voyager - is that 40 miles battery only ? That's as good as most supposedly wonderful electric cars - and you can always pedal !

 

[voyager]

@Scoosh

40 miles ( BUT many more smiles ) using pedelec mode on level 3 ( out of 5 levels ) increasing the mode to 5 gives you unassisted range of 10 miles at 16.5 mph ( 15mph + 10% allowed error )
Now with 2 extra Lifepo4 in the trailer ( total weight of 2 batteries 8kg ) that would give OVER 80 miles of smiles

BUT ..........( why is there always a but )


Recharging them would take 4 chargers and 6 hours or 2 chargers ( lifepo4 and lithium batteries have a different charge voltage for 36v ) about 12 hours

@voyager - nice for longish day touring, charge up at (non-wild) campsite ... what's not to like ... might even have room for a credit card/tent in the trailer !

 

[voyager]

Enough room for the credit card in the panniers , 2 person tent , sleeping bags and stove in the trailer .
Ken can take the fridge , TV and sauna in his trailer

You cant beat a bit of glamping in the summer ...........

The other thing to remember the UK regs on EAPC is that the bike/ trike has a maximum weight of 60kg . the trailer is not counted as the bike and so the additional " luggage " associated with longer rides and camping all go in the trailer .
