I hope it's okay to ask this here. I am wondering if there is a way a first rider could communicate directions or what is ahead to a second rider behind and do it hands free. My first thought was if both riders were using earbuds they could communicate through a phone call. Then I wondered if there is a multi platform iOS/Android walkie talkie app available. I found some but they seem like they all work like an actual walkie talkie where you have to push a button to talk and let up on it to listen which defeats the hands free requirement. The whole idea is to be able to communicate without having to take hands of the handle bars.

Has anyone else thought of an idea of communicating with another rider(s)?

When I walk my bike backwards the front wheel makes a squeaking sound. Has anyone else experienced something like this and what might be the cause. When the bike goes forward it makes no such noise.

Today I finished assembling our two new RadRunner V2 bikes. At home. By myself. Trying to save some money. That included installing fenders. A bit of a chore. I'm plumb worn out. The second one I did this morning was a bit easier.

The only real problem I have had is installing the water bottle holders. The bolts are in the frame fast as if they are glued in place. Or maybe they were inserted in the frame before the paint had a chance to really cure. I loosened one of the bolts but when I tried another it will not loosen. I ended up stripping the head. The Allen wrenches that came with the bike are not the best I think.

The bikes are in working order. So I didn't do half bad.

I have been looking at bike rack options to carry our two RadRunner V2 bikes at the back of our Santa Fe. I have serious doubts about being able to get them loaded on a rack.

I wonder if the Destination E Bike Rack by Hollywood Racks would be the way to go.

I would be interested to hear from anyone who uses this rack.
