Here's my bike when purchased brand-new. It's a Diamondback Insight 1 I picked up from a buddy's bike shop. A very practical, inexpensive, no-frills flat-bar hybrid bike.
After plenty of "upgrades". Converted the flat-bar to a drop set with cyclocross levers. I also discarded all the multispeed cassette and derailleurs in favor a nice single-speed arrangement. The chain-tensioner is a home-made unit I made from a V-brake arm. Added fenders and rear rack for commuting purposes. I also mounted the Turnigy outrunner onto the rack itself.
Here's a close-up of the motor itself with an 11t sprocket from monsterscooterparts. The chain 35# chain is from an old exercise bike.
This is an 110t custom sprocket from King Sprockets mounted to an ENO freewheel. I also have a 16t ENO for non-assisted riding. Tremendous thanks to Luke (LFP) for helping me out with this. The cheap Dicta brand freewheels I used before just could not handle torque accelerating from a stop.
Weight gain is fairly minimal too and the bike still handles reasonably well with the 6s 16AH LiPo pack I have. Because of the only 10:1 gear reduction and 700c tires, top speed so far has been around 54mph (and yes, I will never attempt to match that speed again). I've gone a little over 60mph on one occasion with a strong wind at my back and slight downgrade thus not completely valid. The bike isn't fully-dressed here yet as I removed the controller and batteries while I was still sorting out the freewheel issues. I've been carrying the batteries in pannier bags (which also have the added purpose of hiding the chain and sprocket).
