Overview

The Santa Cruz Heckler SL 90 is a mountain bike designed for trail riding, offering smooth support and strong range from its efficient battery. With hydraulic disc brakes and front and rear suspension, it handles rough terrain comfortably and stops confidently. Its 450W motor and 60Nm torque provide adequate assistance for most trails, though it may struggle on very steep inclines. The bike charges quickly and feels lively for its weight, but its non-removable battery means you'll need to keep the whole bike near a power source for charging.

Best For

  • This mountain e-bike should suit riders who prioritize trail control, off-road capability and comfort on rougher surfaces. Its responsive motor and strong braking system make it a solid choice for trail riders looking for confidence and control in varied terrain. The above-average power-to-weight ratio and efficient battery use also make it appealing to riders who value performance without compromising on range. Riders who prefer a well-balanced e-bike for mixed trail conditions and want a reliable partner for more technical riding may find this bike particularly fitting.

Who Should Avoid It

  • ×

    Riders who prioritize extended range or need to carry the bike to charging points may want to compare alternatives. The battery capacity is below average for similar mountain e-bikes, and the battery is not removable, which could limit flexibility for longer rides or charging convenience. Riders tackling steep terrain may also find the torque and motor power less impactful compared to stronger options in the same category. However, the bike still offers solid trail control, braking confidence, and a responsive ride for those focused on performance over range or portability.

eBike FAQs

Is this bike suitable for technical trail riding and rough terrain?

This bike is well-suited for technical trail riding and rough terrain, thanks to its mountain bike design, front and rear suspension, and hydraulic disc brakes, which provide confident stopping power on varied surfaces. The 29-inch wheels and trail-optimized tires add to its off-road capability, making it a solid choice for trail riding. However, the power delivery may feel less smooth in some situations, which could affect performance on very technical sections.

How does the motor perform on steep climbs and technical sections?

The motor should provide smooth support on steep climbs, but its torque is below average for similar e-bikes, which may make very steep sections feel a bit less responsive. With 450 watts of motor power and a torque of 60 nm, it should handle most technical trail sections adequately, though riders may need to manage their speed and momentum on particularly challenging terrain. The torque and cadence sensor should help deliver more natural assistance, but the lower torque might require a bit more effort on the steepest climbs.
