Found this interesting ebay listing that looks like a Radrover

Sure looks like a Radrover! Oh except for the smaller motor and missing front fork...likely smaller battery (who knows, details are absent). They didn't forget to add a thousand bucks though!

I will confess to liking the rims, but I'll drilling mine anyway!

And also no speed indicator console.

There are a few similar bikes to this, the SSR Sand Viper and the Big Cat Fat Cat

Did you mean this bike? http://www.ebay.com

It has a 500watt motor with 48v Samsung battery, looks very similar to the RR with few difference like no suspension fork, lcd and front light (which I like). Price is $1215.00 but you can make him an offer.
Big Cat is a nice bike but the specs are a little weak for a fat tire.

That was the bike I originally linked to, appears it now takes you to a generic search...old news either way
