OEM Nuvinci automatic transmission (Harmony & HSYNC).

[Trail Cruiser]

I think the easiest way (most user friendly) to use a mid drive is to pair it with automatic transmission like the nuvinci harmony (or H/SYNC in the Bosch). It is also the most efficient since it will always keep your cadence at the optimum window, thus extending your battery range. Another advantage is it automatically shifts down to the lowest gear (first gear equivalent) when stopping and then upshifts by itself when you regained speed (just like your typical car with automatic transmission).

The system is so easy to operate. you just set it and forget it. Even a novice can fully appreciate the joy of riding a bicycle.

However, the cost is prohibitive as an aftermarket product (in fact it's not even openly offered as an aftermarket, only the manual version is available in the stores). I inquired FLX if they can offer Nuvinci Harmony and they said it's too pricey and a little heavier compared to the traditional gear cluster.

These are the ebikes that I'm aware of in the US to offer the OEM nuvinci automatic transmission.

1. Corratec Lifebike (H/SYNC). This ebike is originally designed in partnership with "Dr. Ludwig V. Geiger who developed the LIFE concept, aimed at encouraging people who would not normally ride to improve their life style with exercise." The frame is designed to handle heavy riders to almost 350 pounds. (You can use german to english google translator.)

3. Piaggio Wi bike active plus (H/SYNC, 28 mph top speed).

It can also be applied as a fitness trainer using a smartphone app.

4. Evelo Galaxy ST & TT (programamble top speed, I think), it uses the H8 controller.

5. Tempo electric bikes, a company supposedly catered for the ladies, short people (lower seat tube), for seniors with limited flexibility, and also for the novice and the non-mechanically inclined riders. However, you'll be surprised to find premium quality parts in these ebikes. It uses the more simple H3 controller with 3 predetermined cadence settings (low, medium, & high).

There may be other models that I am not aware of.

A torque sensing system feels nebulous enough to me that i don't think adding an automatic shifting hub is going to firm that up.

Cadence is one thing on an mtb (40-60) and another on a road bike (80-100). That is why I like a hub motor on my road bike and a mid drive TS system for mtb. Both require gear changes for efficiency but it is not that big a deal to select them on the fly.

However if there is ever a jump to MoPed status for e DOT requires the use of an automatic transmission along with a full lighting system and approved rims/tires. The Nuvinci is really the only game in town for that.

I hope this Continental ebike will also sell in the US.

Add the Felt Versa E10 to your list.

There are also a number of other bikes using the NuVinci but not the Harmony, but you could add the harmony to them
Most Riese and Mueller have a NuVinci option

I asked (via Propel ebike store) about the Riese and Mueller with the manual nuvinci, if it can be retrofitted with Harmony or H/SYNC and the response I got from the Germany headquarter is that the drop out does not have enough clearance for the electronic shifter.

Interesting, and good to know, thanks

In general, is it possible to add a Nuvinci Hsync or Shimano DI2 to a Bosch CX middrive and get the OEM automatic gear changing directly in the Bosch controller? I am considering replacing my 11-36 Cassette with a Di2 or Harmony system. Not keen on having a dedicated battery pack and switches.

This is the coolest thread ever! Why arent there more models with the automatic transmission?

These bikes really are my ideal, except for the prices
