I've used this for a lot of stuff I've mounted to my handlebars.

I got the LCD Upgrade for my RadExpand 5, which did come with (I think) rubber spacers.

You could just cut up an old inner tube or some neoprene strips from a rubber boot or some such for DIY spacers. If from an inner tube it may require 1 1/2 wraps, maybe 2 to get good compression.

Or use many wraps of cloth-type hockey tape (aka "friction tape"). It's my new favourite secret weapon.

Also, maybe spiral cable wrap, like this stuff, in different colours and diameters:

I'm not absolutely sure if it would be thick enough.
It's also handy (no surprise) for tidying up wiring and brake cable bundles.

Looking for fenders for my Mission

Looking for fenders for my Mission. Anyone know if third party that fit?

I have an old (!) LCD Display from a Mini that I would like to install on a Rad Expand. However, I don't have the spacers that are required to fit the handlebar clamps of the display to the Rad Expand. The Rad Expand handlebar is a lot thinner than the Mini. Any ideas? Thanks!

Here's the LCD Display I'm referring to: https://www.radpowerbikes.com/products/lcd-display-upgrade?_pos=1&_sid=578b8fbc0&_ss=r

Nice one DickB! Thanks for the reply and that troubleshooting information is really helpful. I do have a multimeter so will give it a go and report back.

Sadly I'm only a few months out of warranty with Rad EU, I purchased the bike in Nov 2022.

I have a Rover 5 so my response is based on this. I had the headlight and taillight go out. The problem was in the controller. The controller has two lighting circuits, one for head plus taillight and one for brake light, with a main board and separate identical smaller boards for the lighting. The headlight + taillight board was bad, and the taillight was bad. I don't know if the bad taillight took out the circuit board or vice versa. My failure differed from yours in that the taillight did not blink.

In your case the blinking taillight might be indication a short. You may possibly have an open connection (broken wire or loose/bad connector) or a controller failure.

If you are under warranty I would contact RAD. If not I would contact RAD anyway for troubleshooting help.

If you want to diagnose yourself, I would start by checking cable plug connections for corrosion and good contact, and any damaged wiring. Then try disconnecting the headlight and use a multimeter to check for voltage going to the headlight with lighting on; also see if the blinking taillight stops blinking. If you don't have a multimeter a cheap one would be just fine. Voltage at the connector and non-blinking taillight would suggest a bad headlight. No voltage suggest a wiring short or a bad controller. Check if the headlight comes on with the taillight disconnected. If it does, that would suggest a short or bad taillight.   

In my experience it is not that important. I charge in my Florida garage, which exceeds 77 for at least 10 months and exceeds 90 all summer. Rover 5 with 9500 miles, I ride every day for 3+ years now and charge after every ride. The battery is nearly like new (I have tested it).

I replaced the handlebars with the lower ones I found online.  The handlebars were an exact match other than the rise.  It's about 2" lower and feels better when I ride.  The fit seems to be closer to my regular bike.  More ride time will tell.
