This has quickly become our go-to multimeter in the Luna Shop where we have many multi-meters to choose from. We are convinced this is the best multi-meter on the market for ebikers.

Do not let the low price and the seemingly simple interface  fool you. This is an advanced meter with advanced features and incredible accuracy in a high quality small package.  This is the most advanced (version c) of the popular UNI-T 120c meter.  Beware there are many clones on the market. Our unit is guaranteed not to be a clone since we bought straight from the factory. 

Small in size, powerful in function, super easy to use at a bargain price, what more could you ask? We at Luna Cycle are proud to offer you this amazing $20 tool.


We think every ebike  builder should have a multi-meter as a critical tool for diagnosis and troubleshooting.  Luna Cycle spent a lot of time sourcing this amazing meter which we think is everything an ebike builder needs in an extremely portable package.


This meter even comes in a waterproof puncture resistant case so you can definitely take this meter on your ebike ride with you, even when riding in disastrous conditions.


We really love this meter and think you will too, having all the critical functions you need, and autoranging to make it incredible easy to use, and very accurate for the price.


You will find no better multi-meter better suited for ebike building and riding even close to  this price point.




This tiny volt meter has auto-ranging which is one of the latest greatest features of the best digital multi-meters which makes it super easy to use.  Autoranging saves you the hassle of having to know which range of value the resistance, capacitance, voltage or whatever electrical characteristic you’re finding falls under. The multimeter finds the value for you. With a manual ranging multimeter (no autoranging), there are preset ranges, and you have to know which range of value your component falls under to get the value reading. This also makes the interface needlessly complicated and hard to use.  No need for your digital meter to look at the example below on the far right which is a meter without auto-ranging.
