I recently got a 2022 Rize RX, which I really like. I decided to do a "virtual teardown" of the bike to facilitate repair, replacement or upgrades to the bike. I wanted to publish the complete specs of the RX so that other owners or prospective buyers might benefit. There may be errors herein, so I encourage any authoritative corrections. I'll give details regarding the components of the bike, but I'll not focus on the Bafang motor and controls, which have been covered ad nauseam elsewhere.

OTHER NOTES
I really like this bike a lot, although I think the wheels are a little funky; I'll probably build new wheels with a 141mm BOOST rear hub at some point. The bike rides nicely and handles well, and is outfitted very reasonably at its price point, which is very moderate for an M620-powered ebike. I'll also be adding a bright flashing tail light for day use.
Here's my bike, set up for urban riding:
One thing I did not like in the original "cockpit" was that the left and right brake levers were not aligned identically, The right lever was butted up to the grip, which gives a natural reach to the lever:
while the left lever was offset by the width of the throttle clamp:
I reoriented this so that left and right levers had the same orientation to the grip. I consider this a (minor) safety issue:
and my thumb is long enough to reach the throttle and controller, so no issues there, except I almost never use the throttle.
Next task: get the cabling in the cockpit cleaned up.

- direct sourcing this battery pack might be problematic due to variations in wiring and charging socket
