The Evolution of VESC Controllers
When it comes to electric bike conversions, the choice of controllers remains a perplexing decision for many enthusiasts. Controllers, often considered the mystical components in electric systems, have transformed over the years. Initially, electric bike conversions relied on proprietary RC controllers, leading to limited power sustainability. In 2014, Swedish electronics engineer Benjamin Vedder introduced the open-source VESC, revolutionizing controller accessibility and programmability.
The Rise of 3shul Motors’ VESC Models
Initially designed for powered skateboards, VESC controllers, particularly those from 3shul Motors in India, have evolved to accommodate various sizes. The latest models boast impressive specifications, reaching up to 126V with a peak of 1400 phase amps. These controllers are gaining popularity for their scalability, making them suitable for diverse electric vehicle applications.
Alien Rides’ KTM Conversion with 3shul CL700 VESC
In the bustling tech hub of San Francisco, Kevin at “Alien Rides” has ventured beyond small electric vehicles to convert dirt bikes into electric counterparts. His 2019 KTM conversion features the CL700 VESC from 3shul Motors. A custom 126V / 30S pack powers a QS 138/70H motor, delivering a remarkable performance. Kevin’s insightful video provides a detailed breakdown of component selections, making it a valuable resource for electric bike enthusiasts.
Rivv’s Honda 450 Conversion: A Canadian Endeavor
Hailing from Quebec, Canada, Endless-Sphere forum user “Rivv” showcases a meticulous conversion of a Honda 450 to electric. While lacking a video, Rivv compensates with a comprehensive series of images depicting the build process. Noteworthy is the integration of the 3shul Motors VESC CL700 and a unique DIY reduction jackshaft, demonstrating innovation in adapting electric components to traditional motorcycle structures.
Unveiling the VESC and its Installation
The VESC, a key component in these conversions, remains a black box filled with electronic intricacies. However, the experienced individuals behind these builds have chosen the 3shul VESC controllers for their reliability and performance. Mounted creatively, these controllers, when potted, offer waterproofing and shock protection. The unconventional positioning, such as upside down under the seat, showcases the installation flexibility.
Crafting High-Performance Battery Packs
An often-overlooked aspect of electric conversions is the battery pack. Rivv’s conversion impresses not only with its 26S / 107V battery pack but also the meticulous planning involved. Utilizing Molicel P28A cells in an 18650 format, Rivv’s CAD-designed battery box undergoes verification with a foam model. The inclusion of custom laser-cut bus plates and grooves in the aluminum plate for a protective battery box highlights the dedication to performance, low resistance, and heat management.
Conclusion: A Glimpse into the Future
As electric bike enthusiasts continue to explore innovative solutions for conversions, the combination of VESC controllers, particularly the 3shul Motors’ CL700, and high-performance battery packs is paving the way for powerful, reliable, and customizable electric rides. These two builds offer a peek into the exciting possibilities and the evolving landscape of electric bike conversions.
