Abt 6 months back, I bought a Mini Velo Bicycle MV7 and now a MV8 is gonna be on sale in the market soon! Bicycle is just like any other electronic products where new models goes into the market rather quickly. As for me, I am quite pleased with my MV7 although a couple more speeds would be great.
Had a evil plan to upgrade to a Shimano Groupset(20 speed!!) and 451 wheelset but the total cost is rather damaging to my depleting bank acc... so I'll just be realistic and probably just upgrade to a bigger OEM crank for less than $100.
