On a regular bike, you can put on a front or rear hub. I would imagine the front is easier to install. But it requires forks that can handle the torque without the risk of catastrophic failure.

So which to choose? They are both good quality so it depends on your criteria.

Get the eZee and the associated compatible controller/battery of your choice if you:
- want more hill climbing torque
- want to start the motor from a standstill
- don't want any drag when not using the motor
- want to use a Cycle Analyst
- now, or later want to customize the setup
- different connectors, battery types/sizes, controllers, etc.
- like to put things together and understand more about how they work
- want to have the satisfaction and future repairability associated with the above

Get the BionX kit if you:
- want an easier, turn key installation
- want to use regeneration (only useful for hilly rides)
- want to easily adjust the level of assist out-of-the-box
- don't see yourself wanting to change the setup in future

So the eZee is a better choice for someone with any ability to work with bikes and wiring. It is just so much more flexible.
