You could add the Magura MT5e to the list. They're hydraulic brakes with motor cutoff function that I currently use on my radrunner plus

Here's my pride and joy: Radrunner Plus bought in January of 2021 with a few upgrades:

- Brooks Cambrium C17 saddle
- Suspension seatpost
- Magura MT5e Hydraulic brakes
- Large crate (RAD)
- Knaap ebike headlight (1200 lumen)
- Motorbike headlight mount

Not yet installed, waiting for motor extension cable:

- 30A sinewave controller + KT-LCD8S display
- 48V 19,2ah battery
- Datex2 device

My favorite upgrade has to be the Magura brakes. it is also by far the most expensive. I paid 200 euro for two sets and another 90 to have them professionally installed. I am trying to learn as much as I can through trial and error but installing these seemed like too much of a jump in required skill-level.

The headlight also deserves some attention. It originally comes from a KNAAP bike, meaning it works with the stock controller. These are normally not sold separately but a local dealer had no problem ripping it off a showroom bike and installing it on mine. At 1200 lumen, I will not be overlooked.

The large crate, a tip: if you are a tall rider and raise the saddle, you can install the crate length-wise which I believe really add to a sleeker aesthetic.

Once I get my motorcable I will finally be able to install the sinewave controller. Sinewave is meant to be a significant upgrade in tech over squarewave but finding detailed results for Bafang motors is impossible. I am very curious to see how much performance I'll gain, and how silent it will be. Note that since I am in the EU I don't see myself getting a bigger motor and getting a higher top speed. My focus is on range and torque. With both batteries installed I should be able to do 80+ km on full pas, averaging 30+ km/h for much longer before noticing voltage sag, can't wait!

Went for an evening ride, shot was taken just east of the city alongside a major shipping canal called "winschoterdiep" - loving this bike so much.
