Assembling a RAD Power RADmission bicycle from late May 2022 - 8 August 2022

RAD Power bicycles is an e-bike company in Seattle.  I finally broke down and got my first e-bike, the RADmission 1.  The big arguments in the e-bike world revolve around mid-drive and hub-drive.  This bike is typical in that it is hub-drive, therefore the motor is in the rear wheel, but it is atypical in that it is a single-gear bike.  No derailleur, no speeds.  The bike has a power-assist option from 0-5, where zero is no e-assist and 5 is full power.  The power-assist works to amplify your pedaling; when you stop pedaling, the motor stops assisting and you coast.  There is also a twist throttle that provides variable assist independent of pedaling.  I bought the upgrade to the control system that displays the wattage that the motor is putting out.  The motor peaks at 500 Watts; other bikes from RAD Power are in the 750W range.  The bikes comes with 2-inch wide tires and disk brakes, so it is comfortable on many trails, including gravel.  The power assist stops assisting above 20 miles per hour, so it is a Class 2 bike in the U.S. because it has a throttle.  The bike was pretty easy to assemble when I followed the printed instructions.  Many or all of the tools are provided, but I often used my own tools because they are of better quality and easier to use.

I am still learning how to ride it well, but here is what I have learned so far.

I use the electronic assist in three ways.  I keep the assist level around 2 and that works well for me in almost any mostly level situation.  Power assist ranges around 100W.  When I hit a hill, I use the throttle to help, and that applies anything up to 500W to get me up the hill.  For steeper hills, I have to stand and pedal to get up.  Finally, I also use the trhottle to accelerate from a stop.  Nominally, this is not needed; the automatic power assist should kick in to help when I start pedaling, but I find that traffic (cars) are often impatient and the throttle-boost gets me going fast enough to stay out of their way or to cross the road (e.g., when riding on a trail that crosses a road).  When hill climbing, I will occasionally boost the power-assist level to 3, but I back it down to 2 for normal riding.  This gives me a pretty good range - I have yet to find the bottom of the battery.
