Yes Super.. those Tekoro’s all have the rubber grip rear wheels geared into whatever makes them ring, ding, click-clack, and tick.
Bertie, Harold, and Theo seem to have the most drag, as none of them are ringers, but any of them all together create a massive amount of resistance, and require an extra powered tender to make a climb.
Those were all of the Chirin de Tekoro, but none of them were the ones with the googly eyes.
