Product Reviews

This is truly a Pro-level power meter at a great price. I started power-based training earlier this year and had placed an order for a 4iii single sided meter, I canceled that order and got this instead. This meter gives you the same accurate data you get from meters that cost three times as much. (Left/right torque, smoothness, efficiency and power) Watteam add-on power meter should be the new standard for power meters at this price. Look out SRM!!!

I've found the G2 to be accurate and responsive across pavement, gravel and rough terrain. I couldn't be happier, and will be recommending them highly! Thanks guys!

It seemed hokey on its face; a DIY power meter? Can they do that? Like, really? They can. I glued a power meter to my own crank arm and... by Jove, it works. Heck, points to Watteam for making a power meter that’s so simple to install and passing the savings on to the consumer.

WatTeam has succeeded at their goal – they brought forth a dual-leg capable power meter below $500 – something that nobody else has done.
