  • http://electricbikereview.com/e-bikekit/e-trike-kit/ The 24″ E-Trike kit comes with a powerful 500 watt direct drive hub motor that’s preinstalled on a 24 inch wheel. You can replace your existing wheel with this one and use zip ties to run cables along the frame for the battery, controller, throttle and display panel. The kit I test here uses the 36 volt 9 amp hour Sealed Lead Acid battery pack and weighs 28 pounds total. You can also get it with Lithium-ion or no battery at all. The kit has been built onto a SUN tricycle to create a Sun electric trike in this video.
