Sounds like the Foodora people have their act together so if a scooter was a winning strategy they would be doing that. Maybe city driving regulations are a problem? A bike with an electric boost could be good though.
Yeah, but e-bikes have very limited range which would quickly become an issue on longer runs. The systems are awfully heavy to pedal unassisted; well at least my Bionx conversion was (have removed it since).
The Bosch system is crank driven, right? In hind sight I regret not going for something like that. The Bionx hub is ludicrously heavy, with short spokes prone to breakage, and required (at the time) its own crappy cassette.
I had to crack the 25 km/h speed limit restriction as going above it required an almost Herculean effort. It should have reverted to an assistance level that offset the weight / drag, but alas.. it just turned off.
What I like the most about this is the sensor system. I am pretty sure there is an actual torque sensor in there. This makes for a very smooth acceleration phase.
Along with a back wheel magnet sensor to keep the speed limit. Last year I made a homemade hack for this.. I used a microcontroller, an electromagnet and a magnetic sensor from a cheapo bike computer to forget every second impulse towards the Bosch system. It worked. The speed limit changed to 50 km/h.
Ended up not bothering to weather-proof it though. 25 km/h is enough most of the time anyway.
