Overview
The Santa Cruz Bullit 90 is a powerful mountain bike designed for serious off-road riding, with a strong motor and efficient battery that provide good range for trail use. Its carbon frame and hydraulic disc brakes offer a responsive and controlled ride, while the high torque ensures confident hill climbing. However, the non-removable battery means you'll need to keep the whole bike near a charger, and the weight makes it a bit less convenient to lift. Despite its high price, the Bullit 90 delivers a capable and lively performance for those focused on trail riding rather than urban commuting.
Best For
✓
This mountain e-bike should suit riders who prioritize off-road performance and trail control, especially those looking for a capable bike for technical terrain and challenging climbs. Its high torque and power-to-weight ratio provide strong hill climbing support and responsive acceleration, making it a solid choice for trail riders who value confident handling and control. The front and rear suspension, combined with hydraulic disc brakes, should enhance comfort and braking confidence on rougher surfaces, appealing to riders who frequently tackle uneven trails. Riders who appreciate a well-balanced blend of power, control, and comfort in a mountain e-bike are likely to find this model particularly appealing.
Who Should Avoid It
×
Riders who prioritize removable battery convenience or seek a significantly larger battery capacity for extended off-road rides may want to compare alternatives. The battery is not removable, which could be a limitation for those needing to charge without moving the whole bike, and the battery capacity is average for a mountain e-bike, which may not fully satisfy those planning very long rides. However, the bike still offers strong hill climbing support and excellent off-road capability, making it a solid choice for riders focused on performance over battery convenience or capacity.

eBike FAQs
Is this bike suitable for long off-road rides?
Yes, the Santa Cruz Bullit 90 is well-suited for long off-road rides, thanks to its strong motor, high torque, and above-average range of 68 miles. The hydraulic disc brakes and mountain bike design provide good trail control and stopping power on rough terrain. However, the non-removable battery means you'll need to keep the bike near a charger, and the average weight might make it slightly less convenient to carry or lift when needed.
How does the motor perform when climbing steep trails?
The motor should handle steep trails effectively, thanks to its 600W power and 85Nm of torque, which are above average for similar mountain e-bikes. The power-to-weight ratio is also strong, making it easier to climb challenging terrain. With a torque and cadence sensor, the motor support should feel responsive and well-tuned to your pedaling effort, helping you maintain control on steep inclines.
Does the bike handle rough terrain comfortably?
The Santa Cruz Bullit 90 is designed for rough terrain, with front and rear suspension that should significantly improve comfort on uneven surfaces. The hydraulic disc brakes provide confident stopping power, which is essential for trail riding. While it's not optimized for daily commuting, it should handle rough terrain comfortably for off-road adventures.
Is the battery efficient enough for regular mountain biking use?
The battery should provide enough range for most regular mountain biking trips, with a range of 68 miles on a single charge. This is above average for similar e-bikes, meaning you can likely ride for several hours before needing to recharge. However, since the battery is not removable, you'll need to charge the bike near a power source, which may be less convenient for multi-day trips or remote trail use.
How practical is this bike for daily use and charging?
This bike is reasonably practical for daily use, especially if your rides are focused on trails and off-road terrain. The 68-mile range should cover most day trips, though the battery isn't removable, meaning you'll need to charge the bike near a power source. Charging takes about 4.9 hours, which is faster than average for similar e-bikes, making it more convenient for regular use.
Who is this bike best suited for?
This bike is best suited for experienced mountain bikers who prioritize off-road performance, trail control, and hill climbing. With above-average motor power and torque, it should handle rough terrain and steep trails confidently. However, the non-removable battery may limit charging convenience, and the price point suggests it's more of an investment than a budget option.
Is this bike good value compared with similar e-bikes?
This bike offers strong performance for a mountain e-bike, with above-average power, range efficiency, and off-road capability. However, the price is higher than similar models, which may make it less competitive in terms of value. The non-removable battery and chain drive also add to maintenance and charging considerations, so buyers should weigh these factors against the bike's strengths.
What are the main compromises of this bike?
The main compromises of this bike include limited storage practicality due to its non-folding frame, the lack of a removable battery which means you'll need to charge the whole bike near a power source, and the need for more maintenance because of its chain drive system. While these factors may be less of a concern for dedicated off-road riders, they could impact convenience for those needing frequent charging or compact storage solutions.
