"Biker" for me usually means motorbiking, though I also have a couple of mountain-bikes... see Trail Bike
My current motorbikes are a Honda CBR600RR ABS 2017 and a Kawasaki Ninja Z250SL.
Previously I have owned: Kawasaki ZX4-RR (Ninja anniversary edition), Honda CRF300 Rally, Honda CBR600RR 2005, Honda CBR600FW, Honda VF750F, Yamaha FJ600, Suzuki GSX750EX, Yamaha FJ750, Yamaha XJ900, Kawasaki Z750 and I passed my riding test on my Kawasaki KH250.

Col de l’Iseran, 2770 m
The mythic big one, the highest road pass in Europe between valleys. Place of rocks, strong sunshine and a chilly breeze. It's always an event to come up here, my first ride was on my XJ750 back in 1986. That was an epic camping trip in the days of European biking before mobile phones and internet booking and before the euro made the currencies easy. Before also the almost ubiquitous adventure style motorbikes and GPS navigation....

Col de la Madeleine, 1993 m
The view of Mt Blanc, 4810 m, is spectacular at the col. It's a classic granite Alpine climb from industrial La Lechère through pine forests, road and views widening out through pretty villages towards the summit.

Cormet d’Arêches, 2109 m
The “other cormet”, more for the hikers, mountain push-bikers and trail motorbikes.
Sumptuous views of the high Beaufortain pastures and the rich red Beaufort cows who supply the milk for the Beaufort cheese. Watch out for
“mud” on the road!

Cormet de Roselend, 1968 m.
This is one of my favourite biker passes, not the highest altitude and the view at the summit marker is a good high mountain but not great. It's not the easiest to get to, it's not on a road to anywhere but it's always a treat to ride, whether on a busy Sunday afternoon or late evening when you might have the road to yourself.
The Cormet de Roselend is part of one of the biker tour routes of Mt Blanc, 4810 m, so plenty of our Italian friends flashing by, out in groups for a day trip in this year's smart kit, hanging off on the hairpin bends and fuelled by strong coffee.

Motorbike riding north through the summer holiday traffic from London to meet with friends from Leicester, I took a scenic route through the Midlands and the Peak District; my return route included the site of “The Daventry Experiment”, where radar was first demonstrated, in 1933.
I'm riding light for a week on the mountain roads of the Alps. No laptop, although I do have my SLR camera but photos will have to wait till I'm back in Marseille..
I left Marseille for a long ride north via the Col de la Croix Haute (1179 m.) to Saint-Gervais under Mont Blanc. A bit of rain towards the end of the day which cleaned the Provence dust off my white leathers and boots but didn't soak me through.
