Yes it does have a full grip throttle. It's quite a nice bike but has a few issues.
I only tested it on a flat supermarket car park so couldn't offer any opinion on it's hill climbing ability. It pulled away OK though, definitely in the moped category of e-bikes.
Pity they weren't represented at Presteigne, plenty of hills there.
I've a Cytronex Claud Butler on order! itching to get out on the new Great Northern Greenway.
