Most of it is actually left over Gorilla Tape adhesive. Hopefully that will come off too!

This thing is a lot of fun to ride and very practical to use.

An effort that could be maintained for hours at a time will get me 23 mph on the flat, and a hard sprint up to 35 mph. This is with the motor disabled while powering through its rotational mass and cogging losses, with the trunk loaded with tools and spare parts. This amount of effort translates into rolling averages between roughly 12-20 mph in a hilly area with lots of stops and traffic, and the torque sensor/computer are indicating human input averages around 250W, but I question its accuracy.

With the motor on, it's basically a 3,000+ MPGe "electric car" in terms of how it can be used on city streets.

Stromer ST1

Not nearly as neat as Toecutter’s velomobile and nothing homebuilt but I wanted to share my ebike. I got a great deal on a used 2015 Stromer ST1 from Blazing Saddles in San Francisco back in November.
After we bought an eGolf I got pretty lazy about taking the bike around town. The ebike has finally replaced pretty much all short trips by car. Did a 13 mile round trip to the dentist on Tuesday and grocery run yesterday. Power assist goes up to 28mph. I can maintain 20mph with easy pedaling so it really doesn’t take much longer around town. Very happy with it.

Mine wasn't built to look neat. It just ended up that way as a result of my design requirements.

The most important thing is that it is functional for your application. And it is.

What kind of range does it get in what conditions?

I don't imagine it's very comfortable on bad roads since it lacks suspension. But with a top speed of only 28 mph, it's something one could most likely live with. I'm guessing it does 750W peak and uses a torque sensor for determining acceleration.

I haven’t pushed the range too much. Guessing it’s around 20miles in 45F weather with full boost. Reducing the power mode makes a big difference obviously.
Ride isn’t too bad. For what it’s worth, the front fork is carbon fiber. The 2.1” tires help a lot.
There is a torque sensor and it ramps in the torque so it doesn’t feel like it’s trying to pull the bike out from under you. If you hold down the plus button on the display it will go 12mph without pedaling. But that feels like a crawl.

Here a few pics of my recumbent bike from my last tour, excuse the dust on the sensor, I will fix that soon.
It's a Radius C4 Tour with some modifications:
Drivetrain:
58T chainring (stock 52T ring just acts as a spacer but could technicly be used)
11-28 7-speed cassette
stock Sachs 3-speed gear hub
Tires:
Continental Contact Speed in 406/28mm
Lights:
Stock dynamo halogen with DIY rechargeable high beam that is as powerfull as my cars highbeams.
Switch is under the seat, battery can power halogen light and tail light via DCD-DC stepdown.

It's a heavy bike made from Cro-Moly steel with rear suspension.
But since I live in the flat lands, weight isn't realy much of an issue to me.

Any bike will benefit from a fairing nose and tail even if not a full body shell. I like the light and gear set up. These are somewhat different from what we see here but effective.

Yea, the drivetrain is rather unconventional.
However it works flawlessly and the efficiency penalty of an IGH is nonexistant most of the time as I'm in gear 2 for 90-95% of the ride.
Some kind of fairing would indeed be nice as I'm living in the flat lands where the weight penalty associated with one wouldn't be noticeable.
Anyway, cargo capavity is rather usefull as well:

You are paying a big penalty for using the 3 speed hub particularly if you don't need low or high range. I had a sachs 7x3 hub. on a race bike and was rewarded with about a 5-6 mph penalty. Only noticed once I removed it.
