First thoughts afetr today's commute - the riding position still needed minor tweeking by raising the saddle, moving it forward a fraction and putting the nose up a few degrees. The slightly swept back riser bars don't make for the most comfortable hand position and a 50mm stem make the bars seem a bit close, so I've ordered the
Lifeline lookalikes of the Ergon grips as I kept automatically moving my hand to non-existant bar ends and may consider getting a properly flat bar such as the
Planet X one I have on another bike.
Still need to get used to riding with panniers as and they don't half add a bit of weight to the back end of the bike (which isn't bad without them) and I kept going over the speed humps on a couple of roads as if I was riding all my other bikes which don't have racks. One Ortlieb easily carried the tool bottle, spare tube, laptop & accessories (in a neoprene sleve), uniform clothing to be washed and a couple of other small bits on the homewards leg, so I could just use one pannier to take stuff in to work at the start of the week, leave it in a locker and then bring it home at the end of the week if I get a saddle bag for the tube, etc.
In use: Surprisingly fast and comforable, partly due to being ordered with upgraded tyres and a carbon seat post added to a Charge Spoon saddle ordered from elsewhere. It may be my more push-on style of riding, but quite a lot of the ride time was spent over the 15.5mph motor cut-off, to the extent that I averaged 15mph over a 29 mile round trip commute (normally 16-17mph on a road bike). In general I wasn't aware of a major assist from the motor, but that may be due to my settings (see below) however the much easier pedaling in traffic and pulling away from a stop was noticable.
Battery usage: To be on the safe side I set it up in 'Urban' mode (the middle of the 3 pre-sets) and only used the minimal assistance level (again of 3). From fully charged last night, I checked the stats on the 'My Smartbike' app the system links to when I got home to find there was still 93% left in the battery with a theoretical 310 miles range

It's safe to say that I could up the assistance level if needed to complete a week's commuting (3 days) without needing to charge the battery.
The idea is that this will be my main commuter bike and certainly will be in anything other than good weather, but I can still see the Van Nicholas being used quite a lot when the weather's good and there's no load carrying needed.
