That doesn’t equate to 30% weight savings
It pretty much does on the battery, compared to a 700wh one, which is probably the new normal, obviously even bigger = even more weight.
YT have been pretty vocal about a 700wh battery & how they weren’t happy with the detrimental effect it had on the handling of the bike (it’s not like it can’t be done, it’s just more cells & there is definitely the space in the downtube for bigger).
Whilst I don’t own one, I’ve ridden one fairly extensively & the Decoy Mullet is one of the best riding ebikes I’ve ridden. I can see why they are sticking with a proven theory. I’d go so far as to say there are very few ebikes with a 600+Wh battery I would chose, just because of the sheer weight of the things going up further & further.
For sure there is a market for full fat ebikes with massive batteries, but the ongoing arms race for bigger & bigger batteries is not something I’m interested in.
