I got the chance to demo a 4-ish year old ('21-'22), green, XL Dew-E DL on Saturday at a LBS.
My first impression, and one I was hoping to find, is that it rode very well and easily with the motor turned off.
This is a big plus for me, as my hope is to start my rides in analog mode, and introduce the assist as I tire, to help further the distance I want to go, or when I have to climb a hill or fight a headwind. I've always preferred to put most of the effort in myself when riding an e-bike.
On flat ground, and of course downhill, I've never felt the need for assist at all.
I also had the chance to test the assist levels on a steep but fairly short, parking garage ramp. I was not disappointed.
I was able to demo a 50Nm, much heavier, Tero 3.0 in April, and it climbed a very long, very steep hill just fine, so I'm confident the 60Nm and 46T of the Kona won't be a problem.
The only cons I found were the handlebar height and the brakes. Handlebars are always too low for me.
The bar height can be raised with a taller riser and bars, and it's likely the brakes seemed weak due to their sitting on a showroom floor for years.
They probably just needed a good cleaning. I always upgrade my brake rotors with 180mm, which would also help with the braking.
There was a third con, and that was the dealer itself. I won't say who it was, but their unwillingness to sell an old bike at a reasonable price, given it had been sitting on their floor for four years, was disappointing and more than a little laughable.
I have seen ads for the older DL's, selling for $1,999, and told them if they'd accept that (+ tax), I'd buy it, but they were only willing to sell it for what they claimed was their cost ($2,500), 4 years ago.
At that price, after 10% Ca sales tax, there's no reason not to just buy a 2025 model with zero miles and a newer battery.
