I've had more electric assist bikes than I'd like to admit. Several years ago I bought my wife a IZIP Trailz AL to get her back into biking then sold it when she didn't want an assist bike. Now she has orthopedic problems and needs assist again for hills - started with a DIY Tongsheng TSDZ2 that I put on her Dahon Briza

But she had problems even with the low step over Briza so I put a front hub motor on a Biria Easy Boarding bike for her - she loves it and it provides enough or more than enough assist even for hilly routes

The 48v rear hub drive that I put on an old mountain bike is only there for testing, eventually I will put it on a tandem bike so we can ride that together again.
Recently I put a 48v TSDZ2 mid drive on an old Schwinn hybrid bike that I like, it has a sturdier frame and wheelset for doing some touring than the BH gravel bike.

Above bike is why I will eventually sell the BH gravel bike. I can only ride one bike at a time and don't need both.
I've had a great time with the BH though, rode it all over Zion NP, up Mt Lemon in AZ, a 3 day 175 mile tour in eastern Oregon last October - lots of fun and excellent performance and range even with a 400wh battery
