The UK Cargo cycle market doesn't seem to know what it wants, and so is mainly drawing on the experience of the European way of doing things.
The majority of British retail outlets that stock cargo bikes are tending to push the Dutch style long Johns/Bakfiets and the American Long tails; often with extensive point of order to point of delivery times (as much as 3-4 months). There have been several valiant efforts by small UK manufacturers such as the now defunct Brox, and the admirable 8 Freight made by Mike Burrows of recumbent bicycle and the Olympic gold medal winning Boardman/ Lotus racing bike fame (and only 4 or 5 miles up the road from me).
After 8 months of extensive research into the potential of the UK Cargo bicycle market and drawing on inspiration from the many smaller manufacturers, homebuilders and users both in Europe and around the world, it is my carefully considered opinion that an estimated split of 80% industrial/utility and 20% goods delivery exists, and almost all imported; therefore the potential Lionís share of the UK market is for my taking. That is why I have spent almost 6 months to date in the design, prototype build, and road test stage, and almost 9 months on the whole project. So far I already have an endurance of ; 100 kg laden, plus rider, 1500km on 6 of the 8 prototypes, which has not been an easy feat when taking into account my other commitments, and I would have really preferred 5000 km on each of the running pre-series prototypes before the production stage.
Electric assist is high on my priorities; not as an ad lib or ad hoc after the fact and after thought conversion, but as a built in and retro fit option: requiring all of what that entails at the design stage and the final in-house production frame approval, and it is proving to be a lot more involved and challenging than it sounds.
