Must have been popular though.Mine is a Pro Rider - no longer stocked [I suspect when the container-full from China is empty, that's it]

However, they are still in business, mine is still going strong after 4 years.
It is heavy, about 20kg without battery - a solid & sturdy construction - but as it's got an electric motor, the overall weight wasn't an issue pedalling... but it was a struggle to lift onto shoulder height bike rack.
