Thanks, everyone!  Great words.  I am going with 22 and not looking back, LOL!

I just received a new thumb throttle attachment for my Radrunner1, although it can fit some other Rad power bike models.  I just wanted to share my relief and excitement here if any of you have my wrist issues.   I admit, I was skeptical....BUT this thumb throttle attachment is AWESOME!   I have a RadRunner1.  I have some arthritis in my wrists and even with light throttle usage for a boost here and there, my wrist bugs me at the end of the day.  This throttle fits like a GLOVE!  I cleaned off my grip with an alcohol swab first to remove any hand oils.  It went on easily, and fits very snugly, without any slippage on my initial two rides!  I love the fact that there is still a little room to use the throttle the traditional way if you desire. ( I love options.) I placed it in a slightly downward position, so I don't bump it when I am at a standstill, but you can place it where best for you.  I got the orange, because I have bumped my throttle accidentally when stopped, and this calls my attention to the throttle to avoid an accidental bump.  In addition, it matches my bikes orange accent colors. My husband has a RadRover, and now wants one in black.  It comes in MANY colors! I found this on Etsy. I have no relationship with this business, other than as a satisfied customer. Seller is Etsy shop 3DPrintsbyTheodore.

My husband has a RADROVER 5, not quite a year old. On ride today, motor power stopped suddenly.  A "P" is showing in his display where the wattage should be.  All connectors tight, battery full.  He had to ride all the way back to trail head under his own power.  We have diligently searched the internet and owners manual and also YT.  Nothing. We called RAD Power Bikes customer service 4 1/2 hours ago, got into the queue to receive a call back and not lose our place in line, and still no call back. That seems excessive. Does anyone have any experience with or thoughts about troubleshooting this issue?  G.G.

 Hello!  I am new here.  I just received a new display upgrade for my year old Radrunner 1 for Mother's Day.   In the display settings for wheel size, it was preset to 22.  RR1 has 20 wheels, which really measure to 22 inches on the stock tires. I am not needing to increase the speed setting, just want to have the most accurate wheel size.  Rad customer service unsure, and after checking said to change to 20. Other advice given on FB and other sites recommend increasing it to 22.  Thanks for any advice!
