We take our turn integrating the electro-mechanical system onto a stock Kona Honzo MTB and come away impressed.
The Revel Propulsion produces 60NM of torque making it slightly less powerful than most OEM combinations. Additionally, the system has a very expensive torque sensing bottom bracket, one of the few DIY products with this feature. This will increase the seamlessness of the transition as the motor’s power is incorporated.
I tested Ergon’s TP1 DIY Cleat-Fitting Tool. Having been trained in correct cleat placement and having fit hundreds of cyclists, this review is based on what I have experienced over many years of bike fitting.
Many excellent bike shops in Southern California already sell e-commuters, with more retailers adding them their inventory every month. So then why would anyone want to assemble a do-it-yourself (DIY) e-bike when there are scores of superb OEM models available? The reasons, many and varied, include the cost savings, the assurance that the conversion of a bike that already fits you perfectly will continue to do so as an e-bike, a new hobby, the feeling of accomplishment and an intimate knowledge of the functional parameters of your bike.
