The Varstrom EKD01 Display has emerged as a compelling option for enthusiasts of electric bike conversions, particularly those working with BAFANG mid-drive motor systems. Designed to integrate seamlessly with UART protocol-compatible motors such as the BBS02B, BBS-HD, and BBS01B, this compact display unit combines functionality with modern design sensibilities. Its growing popularity among UK cyclists stems from its balance of essential features, intuitive operation, and compatibility with popular conversion kits.
Core Features and Compatibility
At the heart of the EKD01 is its 2.4-inch IPS colour screen, which provides clear visibility in various lighting conditions. The display’s waterproof IP67 rating ensures reliability in typical British weather, while the ABS plastic housing offers durability without adding significant weight. Compatibility remains its strongest suit—the unit is engineered specifically for BAFANG mid-motors using UART communication protocols versions 5.0 to 5.8. This specificity makes it an ideal choice for riders upgrading older BAFANG systems or completing new conversions, provided their motor falls within the supported range.
The inclusion of a Type-C charging port reflects contemporary tech standards, allowing riders to power auxiliary devices directly from the display. Three integrated control buttons provide tactile feedback for menu navigation, with users praising the intuitive layout that simplifies operation while cycling.
Functional Depth and Customisation
Beyond basic metrics like speed, distance, and battery level, the EKD01 introduces features uncommon in displays at its tier. The navigation function, though limited to five free trial uses before requiring subscription, integrates GPS guidance directly into the cycling interface. This proves particularly useful for urban commuters exploring new routes or touring cyclists navigating unfamiliar terrain.
Bluetooth connectivity enables smartphone integration through dedicated apps, allowing riders to adjust motor parameters, track ride statistics, and access firmware updates. Multiple user reviews highlight the value of real-time data synchronisation, with one cyclist noting: “The ability to fine-tune assistance levels via smartphone adds a layer of personalisation that enhances every ride.”
The eight-language support (including English, French, and German) caters to the UK’s multilingual cycling community, while the adjustable PAS levels (0-9) provide granular control over pedal assistance. Notably, the odometer reset function addresses a common frustration among conversion kit users who frequently repurpose components between builds.
Installation and Practical Considerations
Compatibility verification remains crucial—the display’s 5-pin female connector suits specific BAFANG motor variants, necessitating confirmation of protocol version before purchase. The unit accommodates handlebars with 22.2mm or 25.4mm diameters, fitting most modern cycling setups without requiring adaptors.
While the compact design conserves handlebar space, some users initially find the 2.4-inch screen modest compared to bulkier alternatives. However, the high-resolution IPS panel mitigates this through crisp text and iconography. The matte finish effectively reduces glare, a feature appreciated by riders frequently navigating between shaded paths and open roads.
User Experience and Performance
Feedback from the cycling community consistently praises the EKD01’s responsive interface, with negligible lag when switching between display modes. The backlit screen maintains visibility during night rides without causing excessive drain on the main battery. Riders particularly value the customisable data fields, allowing prioritisation of preferred metrics like real-time wattage or trip duration.
One recurring theme in user testimonials is the display’s role in enhancing ride safety: “The clear battery percentage readout prevents unexpected power loss, while the speed limiter ensures compliance with UK e-bike regulations.” The Bluetooth-linked anti-theft function, though dependent on smartphone proximity, adds security for urban commuters.
Navigation and Connectivity
The integrated navigation system, while not replacing dedicated GPS units, provides competent route guidance for casual exploration. The five-free-ride model allows sufficient testing before committing to subscription services. Cyclists report satisfactory accuracy in urban environments, though recommend supplementary mapping apps for complex rural navigation.
Bluetooth stability receives particular commendation, maintaining connections across typical urban interference ranges. The companion app’s ability to store multiple rider profiles makes the unit suitable for shared or family bikes, with preset configurations for different cycling styles.
Durability and Environmental Resistance
In rigorous testing across British seasonal conditions, the IP67 certification proves reliable against persistent drizzle and road spray. The sealed button design prevents water ingress during heavy downpours, though users advise periodic cleaning of the screen-edge gasket to maintain waterproof integrity.
Comparative Advantages
Against competing displays in the conversion kit market, the EKD01 distinguishes itself through protocol-specific optimisation. Where generic displays might struggle with BAFANG’s UART communication nuances, this unit leverages manufacturer-specific compatibility for smoother parameter adjustments. The inclusion of a Type-C port future-proofs the system as USB-C becomes the standard for mobile devices.
Community Feedback Integration
Enthusiasts frequently highlight the display’s role in transforming conversion kits into cohesive electric bike systems. Comments like “It bridges the gap between DIY conversions and factory-built e-bikes” underscore its success in delivering OEM-level integration. The ability to clear the odometer resonates with tinkerers who repurpose motors between multiple frames, while commuters appreciate the discreet form factor that deters casual theft attempts.
Conclusion
The Varstrom EKD01 Display positions itself as a thoughtful solution for BAFANG mid-drive conversions, blending essential functionality with modern connectivity features. Its strength lies in protocol-specific optimisation rather than attempting universal compatibility, making it particularly valuable for riders invested in the BAFANG ecosystem. While the navigation subscription model may deter some, the core feature set—coupled with robust construction and intuitive operation—secures its position as a competent interface for urban commuters and recreational cyclists alike.
