4 reviews for Maxwell 24

  1. Rated 5 out of 5

    Jordan McInerney

    All our 10 year old wanted for Christmas was a light weight full suspension bike he could compete on and this is it. We’ve only had the Maxwell 24 for a short time, but it’s already been an incredible upgrade. We rides a mix of jump lines and serious downhill trails, and this bike has been a perfect fit for the way he rides. From the first ride, it felt stable, predictable, and incredibly well balanced.

    The geometry is spot-on — it feels planted at speed but still easy for him to maneuver through tight turns and technical sections. We went with the Pike upgrade and the suspension setup is impressive, soaking up chatter while staying incredibly supportive on big jumps and landings.

    What really stands out is how much confidence this bike has given him from the moment he got on it. The weight and geometry are perfect for him. He’s riding faster, hitting features he used to hesitate on, and carrying speed in a way he never did before.

    Overall, the Maxwell 24 has exceeded our expectations. The build quality, ride feel, and attention to detail are excellent, and it’s clear this bike was well designed. It’s been an incredible investment and easily the best kids’ bike we’ve owned.

    Also worth mentioning — the customer service at Trailcraft has been fantastic. Highly recommended all around.

    Adam Heagy

    From Wyn (8yo rider): “I really like my new bike! It’s real nice, and it makes going over rocks and roots a lot easier. Full suspension makes me more confident, and I really like how it feels. It makes me want to ride even more than my old bike did. I like the color a lot, too!”

    From Dad (bike shop owner w/ 15+ yrs of industry experience): I’m extremely happy with the Trailcraft Maxwell 24! The quality is very good, and it’s clear that it was assembled by people who care about what they’re doing. I’ve built a lot of bikes from various brands over the years, and this was one of the best put together and adjusted bikes I’ve pulled out of a box. I wouldn’t hesitate to buy another Trailcraft in the future, based on that alone.

    My wife and I, along with a family friend who has ridden with our son a good bit, have been blown away by how this bike has stepped up his game. I was a little concerned that moving up in size would result in a temporary loss of confidence, as I’ve seen with a lot of kids as they move up to the next size, but he took to the bike immediately. We’ve only been able to ride a couple times since getting the bike, but both rides were longer and faster than he’s ever ridden, and he rode some sections of trail that he’s historically walked, plus didn’t hesitate to try a technical climb on a section of trail he’d never seen before. For parents who want a high quality bike that pushes their young rider to progress, the Maxwell 24 should be very high on your list.

    Kinley Gardner

    Kinley (8) absolutely loves this bike. She was on a rigid mountain bike prior to this and was riding really well, but I think it was holding her back. We had prioritized light weight over suspension, but with the Trailcraft we get both. After a couple rides at our local bike park she has ridden most of the single black trails (some of them for the first time) and looks super confident. She asked me yesterday, when we are going next.

  4. Rated 5 out of 5

    Jakub Wegrzyn

    Bike is awesome, as advertised and corroborated by online reviews. But responsiveness to questions about our specific needs and implications on build selection and logistics were truly top notch.

    About the bike: I was a little worried that it would be too big for our almost-8-year-old daughter ~4’ 1-2”, moving up from a 20” Woom Off Air 4. It is not. Handlebar is within reach – not “ape hangers” at all – and seatpost is a smidge above minimum on first ride. Choice of chainrings is great – the smallest is great for our kid’s main step-up being climbing endurance, and we can upgrade as she grows and learns.
