The bike's geometry figures tell us that this bike isn't an all-out downhill weapon. But the long wheelbase combined with the low down motor and battery weight did give enough stability and confidence at speed, more than a normal bike with similar numbers.
The high front end, short stem, and wide bar kept the front up and out of trouble and this increased with the big wheel up front. At the back, the beginning of the travel is sensitive and the big tire drowns out some small frequency bumps. There is enough support from the rear suspension to generate speed when pumping and keep the Mig-R feeling positive.
Overall the bike is quiet, thanks to the rubberized noise protection, but the cables at the front needed some tidying up to stop them from rattling on the handlebars.
The only place the Mig-R didn't shine was in mid to long corners where it was average. I put this down to the high-ish bottom bracket (for a 140mm 29er, with 25% sag) and arguably steep head angle. It was tough to drop the bike into turns quickly, and it never felt settled in the corners wanting to stand up. Trying more sag did help but took away some of the responsiveness. The 27.5+/29" combo gave the best and most secure lean angle in the corners and also made it easier to drop the bike in and keep it leaned over.
Did I care about the lack of cornering prowess? For one of the first times, not really. I have been having such a good time during the rest of the duration of the ride trying out technical climbs and trials maneuvers that I didn't mind. Possibly, the solution could be to find a 160mm crank and drop the bottom bracket by 10mm, thus keeping the clearance similar but dropping the rider a little more into the turn.
