This Week Campfire Cycling and the Bike Trailer Blog are focusing on the growing electric bike revolution. Electric Bikes, Future or Fad? is a Campfire Cycling article exploring the bigger picture of e-bike popularity. Obviously e-bikes have some implications when it comes to bicycle trailers as well. An electric assist bike or or kit could certainly make pulling a trailer easier, or enable a greater carrying capacity, but what about an electric assist bicycle trailer?
We received some photos and a story from Dave in Colorado Springs. Dave is a long-time out door enthusiast loves to ride his bike into the woods for recreational activities, but anyone who has been to Colorado Springs knows that just about everywhere you would want to go, the roads point up. For Dave this meant that hauling a day’s outdoor supplies in a bike cargo trailer was going to be a steep endeavor, so to speak.
So Dave got to thinking, having seen growing availability of electric assist bikes and kits got him to thinking, why not an electric assist cargo trailer? So Dave sat down and started designing. Using parts that can be purchased off the shelf he came up with the electric bicycle trailer.
The Design uses a rear hub drive system found in many after market electric bike kits laced into a 20″single 
rear wheel. The battery for the motor is housed under the cargo deck of the trailer. The system can use either lead acid batteries or upgraded batteries such as a lithium ion. The folding tow arm attaches to the seat post for ease of use. Dave says that the trailer can assist his pedaling for up to 25 miles on average paved terrain and up to 30 mph. Not bad for a trailer.
This could be a great alternative for someone who would like the added benefits of electric assist, but wants to continue to ride a traditional bike, You can purchase the plans from Dave at ElectricBicycleTrailer.com. For a more traditional trailer check out either a BOB Yak trailer or a Wandertec BONGO bike trailer.
