In 2023, Kind Shock introduced their first wireless dropper post, the LEV Circuit, in an attempt to take on the electric competition. But is that – and the generous 200 mm of travel – enough to come out on top against the competition in our dropper post comparison test? We found out for you!

Kind Shock is a well-known name when it comes to dropper posts. The Taiwanese manufacturer was one of the first to ever bring a dropper post to market. Today, their product range includes handlebars, stems, and even suspension forks for kids’ MTBs and gravel bikes. After eight years of development, they added an electronic dropper post to their line-up at the end of 2023 – the Kind Shock LEV Circuit. Retailing at € 730, it’s in the same price range as the RockShox Reverb AXS (€ 745) but significantly more expensive than the TranzX EDP01 (€ 500). But does its performance justify the price?

Kind Shock offers the LEV Circuit in 30.9 mm and 31.6 mm diameters. For bikes with a 34.9 mm seat tube, you can buy an adapter from countless online shops and dealers to use the LEV Circuit on your bike. The dropper is available in four travel options: 125, 150, 175, and 200 mm, whereby the travel can’t be adjusted on any of the variants. Only the 125 mm and 150 mm versions are slightly cheaper, retailing at € 690.
Insertion depth is another critical factor, as a long insertion depth could result in a significant portion of the dropper post protruding from the seat tube, thus restricting freedom of movement. At 320 mm, the KS LEV Circuit isn’t the most compact wireless dropper in this test, though it’s only 5 mm longer than the FOX Transfer Neo. However, it costs nearly half as much!
For € 730, you’ll get a dropper with a 450 mAh battery, a remote, a charger, and a USB-C cable (excluding a power adapter). The remote’s design is reminiscent of a miniature car side mirror – compact and functional. In purely visual terms, the KS LEV Circuit relies on a similar design language as the RockShox Reverb AXS, with both droppers featuring a silver collar and an integrated battery near the saddle clamp. This explains the 51 mm stack height. While the KS doesn’t build as tall as the RockShox Reverb AXS (65 mm) or TranzX EDP01 (57 mm), it’s not as compact as the FOX Transfer Neo, which has a 46 mm stack.
Speaking of the dropper head, the LED battery indicator and manual actuation button are located on the top. Unfortunately, these are often obscured by the saddle, making manual operation tricky unless you have very slender fingers. To check the battery charge status, you’ll have to lean forward and read the LEDs: green for 30–100% charge and red for 10–30%, which translates to 3-5 hours of runtime. According to the manufacturer, a fully charged battery should last approximately 8 weeks when used regularly. Fully recharging takes about 4.5 hours, the longest in this test, but this is due to the battery’s bigger capacity.
Important: The KS LEV Circuit features a shake-to-wake function. To prevent the battery from draining during transport, we recommended removing it beforehand.


The internals of the KS LEV Circuit are based on its analog counterpart, the Kind Shock LEV, but flipped upside down, with a motor handling the opening and closing of the control valve. The air chamber can be filled via a Schrader valve on the underside using a shock pump. The air pressure determines the extension speed, with Kind Shock recommending a range of 100 to 180 PSI.
For maintenance, minor tasks such as greasing the wiper seal can be done easily with some basic DIY skills and no special tools. However, if there’s an issue with the cartridge, you’ll have to send the dropper to a service centre, which can be located via the Kind Shock website.
Installing the dropper post is quick and straightforward – almost as simple as clicking the order button. Mounting the saddle is equally easy, using a single 4 mm Allen bolt that tightens two wedges to secure the saddle. There’s also an additional bolt at the front of the dropper head to adjust the saddle angle, similar to the RockShox Reverb AXS and TranzX EDP01.
On the trail, the KS LEV Circuit impresses with smooth extension and compression, and can be activated easily via the remote using minimal force. However, the tactile feedback – the „click“ – is quite subtle. In steep, technical descents, this can be a drawback, as it’s easy to accidentally engage the remote, which could potentially compromise your freedom of movement in critical moments.
The dropper’s reaction time is fast, with no noticeable delay from the moment you press the remote. As for the extension speed, it’s moderate – not too slow, but not as quick and punchy as the RockShox Reverb AXS or FOX Transfer Neo. However, it surpasses the TranzX EDP01 in terms of speed and smooth performance. By the way, dropping the post is effortless.
One thing we didn’t have to worry about throughout the testing session was the KS LEV Circuit’s battery life. While we didn’t push it to the manufacturer’s claimed eight weeks, we recharged the battery after about three to four weeks of regular use. Riding hard for a full week without charging? Bring it on!
One note: the dropper extends slightly if you lift the bike by the saddle. This is something to avoid with any dropper post, as it can cause air to enter the system, which will cause a spongy feel.
Conclusions about the LEV Circuit dropper post
With the KS LEV Circuit, the people at Kind Shock prove that they know how to build electronic dropper posts. Although the system works reliably overall, it has a few minor drawbacks, like the awkward position of the battery charge indicator and the over-sensitive remote. While the extension speed isn’t the fastest in this test field, the LEV Circuit impresses with smooth performance, easy installation, good battery life, and a generous 200 mm of travel – all of this for € 730.
