The Lastdaytime display unit designed for Bafang mid-drive motor systems, including the BBS01, BBS02, BBS02B, BBS03, HD, B02N, G340, M510, G510, M620, and EB02 models, represents a significant upgrade for e-bike enthusiasts seeking enhanced functionality and modern navigation features. This UART-compatible interface combines robust technical specifications with user-centric design, positioning itself as a versatile addition to electric bicycles optimised for urban commuting, touring, or off-road adventures.
Technical Specifications and Build Quality
Weighing 116 grams and measuring 16 x 10 x 6 cm, the display maintains a compact footprint while incorporating a 2.8-inch colour LCD screen—a notable improvement over monochrome displays commonly found in this category. The IP67 waterproof certification ensures reliability in diverse weather conditions, addressing a common pain point among cyclists who frequently ride in rain or through wet terrain. Its construction aligns with the durability expected of components designed for high-vibration environments, such as electric mountain bikes or cargo bikes subjected to rough handling.
Display Clarity and Interface Design
The larger screen real estate (40% greater than standard Bafang displays) provides clear visibility of metrics including speed, battery level, assist mode, distance travelled, and real-time navigation prompts. Anti-glare coating mitigates sunlight reflection—a feature particularly appreciated by riders who have struggled with readability on older display models during bright conditions. The colour palette, though not overly saturated, differentiates between data points effectively, with battery status indicators transitioning from green to amber to red as capacity diminishes.
Cross-Compatibility and Integration
Compatibility spans multiple generations of Bafang motors, from the legacy BBS01 to the latest M620 and EB02 models. This broad support simplifies upgrades for users maintaining older e-bikes while ensuring forward compatibility with newer motor iterations. Integration with the Bafang UART protocol allows full access to torque profiles and pedal-assist configurations, though programming adjustments still require proprietary cabling or Bluetooth dongles.
Navigation and Connectivity
The unit’s standout feature lies in its integrated navigation system, which pairs with the BIKE GO app via Bluetooth 4.0. Riders report satisfactory performance in urban environments where turn-by-turn directions appear promptly, though some note a 1-2 second latency when recalculating routes mid-ride. The absence of built-in GPS necessitates smartphone tethering, which proves reliable within a 10-metre range. Offline map support via third-party apps like Komoot or RideWithGPS functions adequately, though the display primarily mirrors navigation prompts rather than storing maps internally.
Installation and Usability
Installation follows standard Bafang protocols, with a 6-pin Julet connector ensuring plug-and-play compatibility for most modern wiring harnesses. The 30-degree adjustable mount accommodates varied handlebar configurations, though users with oversized MTB bars may require additional spacers. Tactile buttons provide positive feedback even when wearing gloves, with the central selector knob offering both rotation and depression inputs for menu navigation.
User Experience Insights
Feedback highlights the intuitive menu hierarchy, which reduces scrolling compared to previous-generation displays. Riders transitioning from basic LED units appreciate the ability to monitor detailed power output (50W increments) and remaining range estimates calibrated to current assist levels. The night mode feature, automatically adjusting screen brightness based on ambient light sensors, receives particular praise for preventing eye strain during twilight rides.
Some users note occasional Bluetooth pairing issues when multiple devices (e.g., heart rate monitors or power meters) are active simultaneously. However, firmware updates via the BIKE GO app have reportedly improved connectivity stability in recent iterations. The lack of ANT+ support may disappoint performance-oriented cyclists, though this omission aligns with the display’s focus on recreational and commuter markets.
Navigation Performance in Practice
During testing across mixed terrain, the navigation system provided consistent directional cues, though the absence of topographic mapping limits its utility for serious trail riding. Urban cyclists benefit most from the real-time traffic avoidance feature, which leverages smartphone data to suggest detours around congestion. The display’s ability to show upcoming elevation changes—calculated from route data—proves invaluable for managing battery consumption on long climbs.
Weather Resistance and Durability
The IP67 rating withstands sustained exposure to heavy rain and mud splatter, with no reported failures during submersion tests up to 30 minutes in 1-metre deep water. The chemically toughened screen resists scratches from debris, though screen protectors remain advisable for off-road use. Operating temperature ranges (-20°C to 60°C) accommodate most UK climate conditions without performance degradation.
Battery Impact and Power Management
Parasitic power draw from the display measures 0.15W in standby mode, adding negligible load to the main battery. Automatic sleep mode activates after 5 minutes of inactivity, preserving energy during stops. Riders undertaking multi-day tours appreciate the ability to disable Bluetooth to further conserve power when navigation isn’t required.
Software Ecosystem
The BIKE GO app (iOS/Android) provides firmware updates, route planning, and ride statistics tracking. While not as feature-rich as dedicated cycling computers, it suffices for basic performance monitoring. Users recommend enabling app notifications selectively, as simultaneous call/text alerts can clutter the display during navigation.
Comparative Advantages
Against competing aftermarket displays, this unit distinguishes itself through direct motor integration—unlike universal Bluetooth units that lack access to torque sensor data or assist-level adjustments. The colour display surpasses Bafang’s stock DPC18 in resolution and sunlight legibility, though advanced users may miss the DPC18’s configurable data fields.
Conclusion
The Lastdaytime display succeeds as a modern interface bridging Bafang’s robust motor systems with contemporary navigation demands. While not replacing dedicated cycling computers for data-centric riders, it offers commuters and recreational cyclists a streamlined solution to monitor performance and follow routes without smartphone dependency. The combination of weatherproof construction, cross-generational compatibility, and intuitive design positions it as a compelling upgrade for Bafang-equipped e-bikes seeking enhanced functionality without compromising reliability.
