I finally had a go & rode from Mulberry St down to Church St, 13 minutes involving a main road with traffic lights & a couple of "shared use" areas which are classed as slow zones (Expanse ref, Splat!)
It took about 5 minutes to process my pic & driving licence, then I was away for a little scoot up & down Mulberry St. Not sure I like this, I feel a little unbalanced & am not sure what is the best position for my size 10's on the bed of the scooter.
Onto the main road, Myrtle St (A5039) and down the hill in traffic , skirting some roadworks & 2 sets of traffic lights. Not liking this, I don't feel that stable & the cars seem to be giving me less clearance than if I was on a bike. Onto Bold St, which is usually traffic calmed, but is currently pedestrian only. Speed drops to something I'd say was slower than my usual walking pace, but seemed to speed up unpredictably.
Parked the scooter at the Citybike stand in Church St, which as an approved parking spot should give me a £ back on the rental.
That's a general "nah" from me. I'd prefer one of the hire bikes, but these damn things seem to have usurped them.
