Hi ya mate
The masai is a good choice
First things first you wanna change the standard indicators to low wattage Led one as there is no battery on the masai so on idle they dont work to well.
The Masai has a rear wheel problem, where the spokes always come loose.
You can loctite them and keep an eye on them but I just changed the rear to a better heavy duty SDG one.
The stand isn't the best but If got used to mine but I may change it in the future.
A good mod I recommend is changing the sprockets, makes the bike a lot more useble, First gear is pointless on standard.
Have a read through Binge's thread that will give you some ideas.
Mine is there too
Hope this helps
Dave
