I wanted a small ebike with ultra value, I ended up getting the Fiido D4S (20" wheels, folding, 45 pounds, has gears, 36v 10.4Ah, 250w). Price is $800 but I got it on sale for $720. I love the gears, but it came poorly adjusted (chain fell off first ride) so I had to adjust it myself (probably not 100% right, but the Park Tool video got me through it).

I have rode almost 100 miles, though my longest trip thus far was ~20 miles (round trip).

Other caveats:

• the charger doesn’t have a US plug, but can be replaced with a standard 2-prong cord.
• the battery meter is inaccurate, I suspect it errs way too early (maybe even by 10+ miles)
• there is no ignition system, bell (does have digital horn), mirrors, rear light
• also no front mounting (aside from headlight bolt) or bottle mount etc, rear rack is not included by default
• at 250w it is barely an ebike (also EU speed limit), still nice though (helps build muscle but get a bit of help/speed)
• even still, it has a half-twist throttle (that cannot be easily disabled/removed) so is technically class II
• tires (especially spokes) don’t seem to be great, though I suppose it’s acceptable
• battery is not quick-swap (but is an 18650 battery pack, thus likely even more replaceable than other types)
• no suspension
• says on the site (unless in error?) it’s discontinued

I purchased a bike bell for $12 from the local bike shop. I was hoping for a cheaper (or even free) mirror since I mostly use the trail, but no luck so far (though I’m a shut-in so I don’t know anybody really). Same with a storage option.
