the aurem is a slightly longer mod frame than the other frames on the market. the geometry is like this :
Aurem的長度是小車中稍長一點的車架。他的幾合如下：

1020mm wheelbase
+75mm wheelbase
350mm chainstay
71.5 degree headangle

The advantage of having a slightly longer mod is that you get a lot more leverage when you are standing on the back tire. This combined with the higher bottom bracket height makes the bike feel amazingly light when you are side hopping or gapping. The extra length makes pedal moves slightly easier, you get more reach when trying to span gaps with both wheels.
些微長的車架當你在點跳時會透過槓桿原理獲得更多的力量，如此可以結合高的BB讓車子感覺異常的輕盈和好操控（側跳、跳遠等）。這額外的長度讓你的踏板更好踩動，你可以透過這樣的長度，讓你雙輪能夠衡跨在更寬的溝上。

The disadvantage of having a longer mod, is that bunnyhops are very hard when you are shorter.
長小車的缺點就是你豚跳會比你用短車來得困難。

There is also a rockman manus frame, which is a shorter version of this frame, with an even higher bottom bracket. I haven't tried it yet, but i will build one for my self to test:)
那邊也有一個 rockman manus 車架，它是短版的車架，BB高度稍高。我還沒試過那台，不過我還是會自己組起來給自己測試。
