Topeak makes some nice air pumps, their Race Rocket MT is a good compact one for MTBs. But not for Levo SL, the mounting bracket does not fit the frame. 
But I have a 3D printer and time on my hands so I made a new bracket. And it almost fit. Model 2 fits perfectly!
It also requires longer screws (4-5 mm longer than the original M5 x 10 mm). Do not use a screw that goes into the hole deeper than about 8 mm, there is something solid at 10 mm and it is probably the battery!
