PUSH TRAILER Interest

We are applying for a 'Green' grant shortly and our site has generated a lot of interest and plan sales. Anyone with an interest should visit our sit...

Powered Push Trailers

The old thread I started on this project has gone stale......So I'm back to show the latest Push trailer design I've done and to see if anyone else is into this concept. I used a Nine Continents System on 48 v 12 Ah SLA.........about 20 mile range with pedaling and 17 mph on flat hard surface with n...

Re: My PUSH TRAILER

I have moved on to a new design that will allow simpler construction for my published plans and future kits.. So, the unit pictures above is for sale! I will sell it without batteries or drive unit. In otherwards, the complete 'Trailer' assembly only. It can be used as an unpowered, straight towing ...

Re: My PUSH TRAILER

Yes, of course the seat post mount swivels side to side and up and down.....a universal joint, if you will. One wheel was a must for me..... Less friction, narrow track, and it handles great! You really don't feel much of anything behind you. The center of gravity is so low that stopping and low spe...

Re: My PUSH TRAILER

Well, I just got back from a short run with the finished unit....about 5 miles. Sweet.....it handles ten times better than the first version. But, now I move onto an even simplier version built with off-the-shelf items form Home Depot or a good hardware store.....far less welding, and no fancy metal...

Re: My PUSH TRAILER

Yes ...... actually I have a 60 yard long, super steep driveway .....but that's not the reason I went the way I did with the hitch design. First off ....IT'S EASY! No fancy hitch system required. Just a pivit on the seatpost. I have found the seatpost mount to work great, actually. The leverage for...

Re: My PUSH TRAILER

Here's a CAD image of the new frame.
The battery boxes hang on both sides of the wheel under the deck.
Three point parking with folding yoke for storage.
Bungee hooks will be added to the sides of the frame.
Deck surfaced in Sheet PVC.

Re: My PUSH TRAILER

Well....after several rides of over 10 miles each, both with and without cargo I have come to two conclusions: 1. The center of gravity is too high when loaded for my needs. 2. I don't have enough cargo capacity. So........I 'm half way through the build of a new frame. It will take care of both of ...

Re: My PUSH TRAILER

Let me try to answer all your questions.... <nomad85> The other bike is a 36 volt system and isn't as fast (about 18 mph on the flats without pedal)....but it has great range with pedal assist. I haven't gone on a long run with the trailer yet. <dontsendbubbamail> Tire wear may be an issue. It's rig...
