That’s interesting Ellen. First of all congratulations on some innovative thinking about using your E Rider to help you with your job. Unfortunately I can’t give much useful advice.
We don’t sell trailers ourselves and I do not have any experience in using them. I do know that luggage trailers are towed behind electric bikes quite a lot in the Untied States and there is even a website about the use of electric bikes as cargo vehicles. We put a link to it from our Facebook page recently and you may like to have a look at it.
When we were exhibiting the E Rider at the 2014 Ideal Home Exhibition I was asked several times about pet transport on the bike. I didn’t have any information at the time, but in fact there are plenty of trailers available for dogs, cats, etc. Here is one example which is reasonably affordable:
As we have not tested any of these products we do not know whether they would fit safely on the E Rider and we ahve no information about their quality or how well they would work with the bike.
As there is potentially some interest in using trailers with the E Rider for a range of different purposes it would be very interesting to hear from anybody who has used trailers with any sort of bike or electric bike. Please let us know what your experience has been.
