where can i get one of these

[ghostbiker]

either the one in the vid has not been set up right or its not a acumen one (dont think it is acumen as it looks to wide) it was jumping up and down the gears while it worked out what change had been done.
i use an acumen one and it works a teat one set up (takes 2 mins once you read the simple instructions)
with the wire loom its plug and play, without the loom its a few solders.
