- Front motors are generally easier to install. No messing with gears, cog clearance, etc.

- For a short wheelbase bike, a front motor can help with weight balance if you have a battery pack and/or your gear on the back

- If you have cheap, cast aluminum forks, they may not withstand the stress of a front motor. In that case it is good to install a rear motor, or to replace your front fork with a chromoly steel one.

- A rear motor is usually a bit more “stealth” for those who don’t want it to be obvious that they have an electric motor

- Most rear motors (except BionX) are limited to 8 speeds due to clearance issues. All the rear motors use freewheels, not cassettes. We need to explore the potential for the BMC to accept 9 speed, but I kind of doubt that it will. Also, rear motors don’t work with a bike that has internal hub gears, like the Shimano Nexus.

- A front motor can make the steering feel a bit heavier/slower. With the lighter geared motors (like eZee, BMC) it is not so bad, but with heavier motors like Crystalyte and Forsen, it is noticeable. Some people don’t mind, others do.

In the end, it really depends on your bike, and how you use the bike, to determine the front/rear installation question.

ps – and yes, the KidzTandem is a lot of fun!

Also, that Kidz Tandem in the shop looks very fun!
