I wonder if these are the tires Rad will be dispatching to effected RW4 owners?
So far so good. 15 days in. About 150 miles. Been taking it easy but gradually getting more confident on them. Quietness, less rolling resistance but equal stability still stands. In addition, they handle wet conditions better and cornering is out of this world different.
Still early days, of course, and I'm using a different cargo bike more at the moment because I want want to be cautious and the kids get colder and wetter on the RW4 as the Conestoga doesn't cover legs (our other cargo is fully enclosed bucket). But, so far, these are proving themselves more than capable.
It also helps that the Speedster is a brand that has been used for years on other bike types (starting I believe with BMX) so I don't feel like I'm using something entirely experimental, which in reality the original tires are.
