New Bike: 5mile commute, occasional touring, alfine8 Hub with flat bars

I have just been through a similar decision for my commuting bike. I have 8 miles each way, most on a dedicated cycleway with just the final mile on roads. For years I used a 3 x 9 of an obscure but highly specified make that was an insurance replacement. That lasted 13 years of all weather commuting before the frame cracked. I replaced that with a Peak Trail 1 that did fine until the inevitable drive train wear needed everything replacing. I was now fed up with replacing chains, cassettes and chainrings and as the crank also needed replacing decided to look at a hub setup.
This is where it gets interesting as there are some Gates Carbon Drive bikes out there under the magical £1000. I specifically wanted an Alfine hub due to the mileage and the low maintenance and cleanliness of the Gates Belt appealed. I finally decided on a Cube Hyde Race and was able to pick up a 2017 model for just over £600.
I have only done a couple of weeks but my impressions so far a great:
It is very quiet
The 8 speed Alfine, although slightly lower geared than the 11/46 with a 44 tooth front provides all the gears I need.
The bike is light and I am also surprised at how quick it is.
The new Alfine thumb changer feels very natural. The old twist grips were one of the points that had put me off in the past.
Rigid forks am not as forgiving as the Suntours on the Peak Trail but it is only in a few places and the lower maintenance outweighs this.
I just hope that the Afline hub and Gates Belt match up to the longevity that is claimed.

The dynamo hubs with lighting would be a real plus and worth a bit more cash for. The cube travel and Marin presido 4 look like good options.

I can highly recommend the Cube Hyde. I used to have the Pro before it got nicked and it was a great bike, possibly one of my favorites I've owned. I used to ride it on the potholed roads to work and on light trails/forest paths etc, and didn't once wish it has suspension forks as the big tyres give a good amount of cushion. The only thing I didn't like was the stock saddle, but a Charge Spoon soon sorted that.

The Pinnacle Lithium Alfine looks good too and would be on my list if I was after another flat bar hybrid.

@roylovell - You need to learn where to position your cranks when turning so your feet don't catch the wheel (turn to the left have your right crank back, turn to the right have your left crank back)... and also cycle on the balls of your feet rather than the middle. Should be less of an issue as you get used to the bike as you'll find you only do sharp turns at low speed anyway. You won't be turning that extremely at speed
