Frequently Asked Questions
How do I know if my motor system is UART and compatible with this display?
UART is the protocol used by Bafang BBS-series mid-drives (BBS01, BBS02, BBSHD) and Bafang hub motors (G020, G0900, G062, H400B, H640, H550), as well as Varstrom and SUTTO hub motors. If your motor is one of these, you have UART. To confirm for other motors: check your existing display or controller for UART labeling, or look up your motor model's specifications. If your system uses a Bafang 860C or 850C display, those use a different Bafang protocol variant and this display is NOT compatible. If your controller uses CAN bus (common in many non-Bafang systems), this display is also NOT compatible. When in doubt, check the connector - UART systems typically use a 5-pin or 6-pin M5 waterproof connector matching the harness on this display.
Which of the four models should I choose?
Choose EKD01 Bluetooth if you want smartphone app connectivity for wireless settings, ride logging, and diagnostics. Choose SW2-M58 Color if display visibility is your priority - the color TFT is significantly easier to read in sunlight and at a glance. Choose DZ40 Mini if handlebar space is limited or you prefer a compact, minimal display (city bikes, folding bikes, clean builds). Choose Bafang DPC18 if you are replacing a failed DPC18 and want a native Bafang like-for-like swap with the original menu structure.
How do I install this display - do I need tools or special software?
Installation is plug-and-play for matching UART systems. Connect the M5 waterproof display cable to the corresponding connector on your motor controller harness - connectors are keyed and only mate one way. Mount on your handlebars using the included bracket. Power on and the display initializes automatically. PAS level configuration is done through the display settings menu - see the user manual for the button combination. No laptop or software is needed for basic setup. For advanced parameter changes (wheel size, speed limit, motor tuning), the EKD01 Bluetooth model supports wireless programming via the Varstrom app; other models require a USB programming cable and Bafang PC software.
Is this display compatible with 52V and 60V battery systems?
Yes - the Varstrom display supports 12V through 60V, explicitly covering 52V and 60V high-voltage builds. Many budget displays are only rated to 48V and will show incorrect battery readings or be damaged by 52V/60V batteries. When setting up, configure the battery voltage parameter in the display settings to match your actual battery voltage for accurate state-of-charge percentage display.
What does IP67-IP68 waterproof mean for riding in rain?
IP67 means tested for submersion in 1 meter of water for 30 minutes - in practice this covers heavy rain, road spray, puddle splashes, and all normal wet riding conditions. IP68 (where applicable by model) covers deeper or longer submersion. Both ratings are more than sufficient for commuting and off-road riding in rain. The M5 waterproof connector protects the most vulnerable cable connection point. Do not pressure-wash the display directly - high-pressure water can force past seals. Clean with a damp cloth or low-pressure rinse.
What is DDP shipping and which countries does it cover?
DDP (Delivered Duty Paid) means Varstrom pre-pays all import duties, VAT, and customs fees before shipment - you pay nothing extra at the border or upon delivery. DDP covers these 23 EU countries: France, Spain, Netherlands, Italy, Bulgaria, Belgium, Latvia, Poland, Denmark, Finland, Portugal, Sweden, Slovakia, Slovenia, Greece, Hungary, Czech Republic, Lithuania, Luxembourg, Romania, Ireland, Estonia, and Croatia. For US customers, imports under $800 are typically duty-free under the de minimis threshold. For UK customers, standard UK import VAT may apply depending on declared value. For countries not listed, confirm local customs requirements before purchasing.
