Bowflex vs REP vs Titan Adjustable Kettlebell: Specs and Prices
Bowflex, REP and Titan each sell an adjustable kettlebell, and they change weight in three different ways: a dial, a push-and-twist mechanism and plates. On the pages we read on November 8, 2026, prices ran from $149 to about $225, handles from 28 mm to 35 mm, and warranties from one to two years.
Quick answer: pick Bowflex if you want the quickest weight change and a 2-year parts warranty, REP if you want a competition-style shape with a stated 34.6 mm handle, and Titan if you want a cast iron bell. We have not tested any of them. This is general information, not medical advice.

Which adjustable kettlebell is cheapest?
The Bowflex at $149 was the lowest regular price we saw, with REP’s 8 to 16 kg bell $0.99 above it at $149.99. REP’s 16 to 24 kg bell costs $219.99 and Titan’s competition-style bell lists at $224.99. Titan also sells a 20 lb adjustable bell, which was $104.99 ($93.97 on sale) on the collection page. Prices were moving with early Black Friday sales, so compare them again before you buy. For how adjustable bells compare with ordinary ones on cost, see how much a kettlebell costs.
Which adjustable kettlebell is easiest to adjust?
Bowflex’s bell has a dial that changes the weight with a turn, and a buyer review on its page praises it; that is one review, not a test. REP’s is a push-and-twist mechanism with a nylon fastener for each weight setting, which REP says keeps rattling to a minimum. Titan’s two bells use plates: the competition-style bell needs the supplied hex key and wrench, and the 40 lb bell has numbered plates and a quick lock mechanism. If you plan to change weights often in a workout, the dial and twist designs are the ones built for it; plate-loading usually takes longer.
Which adjustable kettlebell has the best handle?
Handle diameter is the clearest spec we could compare. REP’s kilogram models have a 34.6 mm handle and Titan’s competition-style bell has a 35 mm handle, which is the handle diameter the IUKL’s 2013 rules give for a competition bell (the 2017 rules list 32 mm; see competition vs cast iron kettlebells). Titan’s 40 lb bell lists 28 mm, thinner, and our adjustable vs fixed guide notes that Garage Gym Reviews found its handle thin and slick. Bowflex’s page did not state a handle size. How a handle feels depends on your hand, so a measured diameter is a guide, not a verdict.
What the ratings say, and what they do not
REP’s page shows 4.9 out of 5 from 374 reviews and Bowflex’s shows 4.8 from 1,587. Titan’s pages show 70 reviews for the competition-style bell and 37 for the 40 lb bell. These are ratings on each seller’s own page, so they are not independent tests, and different sellers collect reviews differently. For independent testing, our adjustable guide draws on BarBend and Garage Gym Reviews.
How to choose between them
- You want the fastest weight change: the Bowflex dial or REP’s twist.
- You want a competition-style shape and handle: REP (34.6 mm) or Titan’s competition-style bell (35 mm).
- You want a cast iron bell: either Titan bell (the 40 lb was $159.99 on backorder; the 12 to 32 kg was in stock).
- You are unsure what weight you will use: an adjustable bell is a way to avoid buying twice, but read the return policy before you order.
