Bristol GB I like bikes
Easily laced to a rim as the flanges are equal distance from the center so equal spoke lengths on left and right. Wheel has performed well for me in Bristol changing up at about 10-15mph on a 700c rim. I've paired it with a 42t chainring and that seems enough to get me up short to medium inclines and have enough left to get going on the flat. The brake works very well but best paired with a front brake if you're using on long hills as I've heard they heat up and become less effective when used for long drawn out braking.

I'd totally recommend. You feel totally in control through your legs similar to a fixie, have a little extra for the hills and makes for an attractive bike without the cables. I've just bought another for a shopper bike I'm building.

Be ahead of the curve and get one!
You might say it's a little heavy but it's hardly surprising

London GB
Really easy geared hub. It shifts a little too early but I believe with a bit of adjustment of the internal springs you can alter it moderately easily.
When it switched to the higher gear it starts to ratchet. Which is a bit annoying. I thought it would have been better to be silent in the top gear and ratchet in the lower but that's maybe just me.

Auto shifting you can rely on
This one's a no-brainer. When riding in dense city traffic, you need to concentrate on the road, not on your shifters. With Sram's Automatix two-speed hub, you can focus on your lane, and the hub will change gear automatically for you based on your speed. There's no shifter, because the centrifugal clutch chooses your gear automatically. It's a fantastic system for riding around town, with a minimum of terrain changes. If you're on hillier ground, check out the i-Motion 3 instead.
Automatix gets you where you're going, and the centrifugal clutch changes the pace along with you. It delivers automatic two-speed shifting, no shifter required. Sram Automatix eliminates the distractions for a ride that's safer, easier, and more fun!
