Funnily enough I was idly checking other brands to see what rivals there are to the Creo 2 when I saw the Revolt e+ had a Shimano motor. Here's the UK website page but it might auto click through to the North America site when you try and open it!I may be wrong here - it happens - but I believe any Revolt e+ bikes are a couple of years old. They have not been available in the US for maybe two years, and searching their website yields nothing. My LBS, Giant dealer, agrees.
With that said though, in I believe in or around 2022 it seemed like they really didn’t know what they were doing. The Revolt e+ web page itself referred to BOTH the Shimano and the Yamaha motors as the power source in different sections of the page. It seemed like they intended to switch, but ended up walking away from the whole thing. Either way, it was referred to as Syncdrive.
I did see and test an actual Revolt e+ in the shop in Lake Placid on one of our frequent visits up there, and liked it quite a lot as the replacement for the excellent Toughroad ebike. Almost bought one, but ended up going a different direction to the Creo.
