Trying to get the RadRover on a Seattle metro bus

Sai Kodi


I am new to the site and new to electric bikes. I just bought mine a couple of days back and am loving it. So far I have put 15 miles on the RadRover and oh my gosh its amazing! I just love it.

Having said that, since it looks like I am liking it a lot more than I thought I would, I am planning to use it for my commuting needs - home to bus park & ride and back in the evening. Its 4 miles each way and it should be a breeze on this thing.

I looked up Seattle metro bus requirements:
  • Wheel sizes of 16"-29" allowed - RR has 26" which is good
  • Wheel base of up to 46" allowed - RR has 46" which is good
  • Tire widths of up to 3" allowed - RR has 4" - not good
  • Weight limit of 55 lbs allowed - RR is 54lbs without battery which is good
Technical specs taken from:
Seattle Metro bus requirements:

So I can put up with removing the battery every time I put it on the bus to deal with weight limitations. However, the tires wont fit. Are there any good 3" tires that would fit the RR? My needs are strictly for commuting purposes on streets and pavements and off-road requirements are absolute zero.

Is it a possibility to swap the 4" tires with 3" wide tires for the RadRover?

Some folks here really like 3" hookworm tires on their Rover. Likely my next tire when I wear out the originals.

You might also find out what Seattle means when they say 3 inches. Like is the tray 3.5" to accomodate 3 inch tires, or is it a 3 inch wide tray?

The last set of Vee Rubber tires I bought are advertised at 4.7 inches, but are barely 4" on my rims. I knew that going in.

Unfortunately more likely than not it won't matter if you put a skinnier tire on the radrover, the rim is still going to be too wide for any bus bike rack system. They simply aren't built for fat tire bikes.

The radrover wheel is 3.5" wide. I'll need to confirm this but regardless it's too wide of a wheel to begin with. I believe the tire, when inflated, comes out to about 4.25" wide. They just BARELY fit my rack tray which is good up to 4.5" wide.

Okay. So there is no way we can put it on a bus even with skinny tires? I will call the metro tomorrow to get more details on the rack system.

Great thanks! I will give it a try. That way we know what will fit and what not. Excepting the tires everything else looks to match the requirements. :) I am optimistic we can do some changes to the tires and get it loaded on to the bus. :)
