NORCO SIGHT VLT BOSCH A2 SPECS OVERVIEW
The Norco Sight VLT Bosch A series is made with a quality aluminum alloy frame featuring 150mm of VPS Horst Link suspension and a mixed-wheel setup only. With the Bosch Performance Line PX drive unit offering solid power, and a durable frame designed to offer stellar handling at its price point, the Sight VLT Bosch A proved to be a competent all mountain eMTB.
BOSCH PX EBIKE SYSTEM SPECS
Norco is the only brand included in our shootout that is using the Bosch Performance Line PX drive unit. Tipping the scales with a slightly higher 2.9kg weight figure compared to the CX drive unit, the PX produces 90Nm of maximum torque with up to 700W peak power at 600% assistance.
The PX had a slightly different characteristic on the trail compared with the more common (in premium eMTBs) CX drive unit, lacking overrun and giving a more direct feeling.
Powering the Bosch PX drive unit is the 600Wh PowerTube battery, which is fixed inside the downtube of the alloy Norco frame to give the lightest overall setup. Riders looking to cover more ground can use the Bosch PowerMore 250Wh Range Extender to boost the battery capacity, in place of a water bottle. Using the Bosch 4A charger, this 600Wh battery can be charged fully in just under 5 hours. Bosch recently announced a 12A fast charger is scheduled to be released by the end of 2026, which should give 50% charge in just 42 minutes.
The Bosch LED System Controller and Wireless Mini Remote give a minimalistic cockpit setup for the eBike system. Riders looking to obtain more information during the ride can purchase a bar-mounted display aftermarket, or use the Bosch eBike Flow App to obtain the stats through their phone. The Bosch app also gives tuning potential for the drive unit power modes, over-the-air updates, and some security functions.
NORCO SIGHT VLT BOSCH A2 GEOMETRY
Norco gave the Sight VLT Bosch A eMTB a geometry set that is likely to please a wide range of riders looking for a do-everything eBike. The sizing system uses numbered sizes 1 to 5, with small gaps in frame reach and stack that should allow riders from 5’1” to 6’6” (155cm to 198cm) to find a comfortable fit. Our crew enjoyed the cockpit feel provided by the 490mm reach on the Size 4 frame, with heights ranging from 5’10” to 6’2” (178cm to 189cm).
The Sight VLT Bosch A features rear end lengths that add 4mm to the chainstay as you move up each size, combining with progressively steeper seat tube angles to give more consistent weight bias throughout the range.
Using the Ride Aligned system, riders can input their data to be recommended the correct size and a suspension and tire setup to hit the trails with a good initial approximation. Ride Aligned is one of the best systems of this type in the industry, and The Loam Wolf crew has learned to trust that its suggestion will get us in a good ballpark on a Norco bike from the off.
NORCO SIGHT VLT BOSCH A BUILD OPTIONS
Norco offers three build specs in the Sight VLT Bosch A, from the A3 at $4,799 to the A1 at $6,599. We tested the Sight VLT Bosch A2, retailing for $5,699 and with a solid entry-to-mid-level spec.
The alloy frame and Bosch PX drive unit with 600Wh are suspended by a RockShox Lyrik Base RC fork in 160mm, and a Super Deluxe Base w/HBO shock as standard. We received a Super Deluxe Select+ shock for our test bike, featuring additional low speed compression adjustability. The drivetrain is a mix of Shimano Deore with a Deore XT mech in 12spd, and the brakes are Shimano Deore with a 203mm front and 180mm rear rotor.
The cockpit is Norco in-house 6061 alloy kit, with a TransX dropper post in 200mm length on the S4 tested topped with a WTB Solano saddle.
Rounding out the specs, WTB KOM Trail i30 wheels are laced to Shimano hubs, and wrapped in the stellar Maxxis Assegai EXO+ and Minion DHR II Double Down tire combo as standard. As with all of the bikes in our 2026 eMTB Shootout, these were replaced with a Schwalbe Tacky Chan Gravity Pro and Magic Mary Gravity Pro tire combination to give dependable and consistent grip across the test fleet.
The Norco Sight VLT Bosch A2 in size S4 weighed 52.3lbs (23.7kg) with our Schwalbe control tires.
BOSCH PX DRIVE UNIT PERFORMANCE
- Pure Power: Compared to the other units, the Bosch PX drive unit is the underdog, though none of our testers disqualified the bike because of it. The system will not be propelling riders to the top of any podiums, however it offers all the power you need to climb your way to the top. When compared to other units, the power of the PX is most susceptible to cadence. It drops off significantly when your RPMs drop and thus requires the rider to shift a bit more often or to use a bit more of their own muscle, heaven forbid. If your cadence is up, the PX will give you plenty of juice.
- Control: Bosch’s Flow app gives riders a lot of control over the amount and delivery of power as well as the feedback and responsiveness. Bosch do a good job of providing a capable motor, however we did notice that on the most extreme of technical climbs, we missed the extended boost that the CX and other drive units feature. Overrun is a great advancement in eBike motor performance, helping to maintain drive when pedaling isn’t an option, such as when ascending steps and ledges or pedaling through chunky terrain. The system still packs some impressive tech, sensitivity and will handle challenging terrain just fine.
- Perceived Efficiency: The lower power of the PX meant that it could really stretch the range of the 600Wh internal battery. It seems like a rather efficient system. If you’re looking to ride in higher power modes or keep up with CX/Avinox bikes, you may want to consider a PowerMore Range Extender.
- Noise Up and down: The PX is a bit louder in terms of noise than the latest generation CX, but it’s not a huge factor in our tester’s opinion. When bouncing between the Norco Sight VLT A and all the other bikes, noise wasn’t a big talking point.
- Ecosystem: The Bosch ecosystem is solid and while the PX may not be for everyone, it’s certainly a capable drive unit that offers a nice blend of assistance without the long overrun which can remove some of the technical challenge of climbing ledges some riders enjoy challenging themselves on.
NORCO SIGHT VLT BOSCH A2 CLIMBING PERFORMANCE
Hopping aboard the Norco Sight VLT A, our testers instantly felt at home. “It feels like the rest of the bikes in their line,” is the kind of compliment many brands strive for when they design a budget-focused mountain bike. The Sight VLT Bosch A feels every bit a Norco as their bikes that cost twice as much, and that’s a nice thing for riders who are looking to ride hard while not stressing about how they’re gonna pay for groceries next month.
Moving away from the stellar geometry, suspension feel and general comfort of the Sight VLT, the biggest talking point of the Sight VLT is the Bosch PX drive unit. The unit admittedly packs a lighter punch in terms of watts and torque, but it never prevented us from having a good time and riding with the crew. With the reduction in power, we found that the unit thrived at higher RPMs and dropped power notably once the cadence slowed. Example scenarios would be exiting steep and very tight switchbacks. If you come to a near stop or slow way down, you’ll be best served by shifting a gear or two, or be prepared for one or two harder pedal strokes until speed and cadence pick back up again. We know, a dreadful thought… but we are here to analyze and be critical, not give you David Goggins motivation on why you should work harder.
The other notable area which may be a deal-breaker for some is the lack of overrun that the PX unit offers, but it wasn’t for us. When you stop pedaling the PX, it stops working, unlike some bikes which continue driving power for up to six feet. This means that ledges or steps require a bit more effort and technique, kind of like how we used to do it before eBikes existed. All that to say, we still made our techy climbs, it just rode a bit more like a regular bike.
NORCO SIGHT BOSCH VLT A2DESCENDING PERFORMANCE
That “Feels like a Norco” feeling translated to the downhill trails even better than the climbs. Often times, budget-focused bikes can leave more demanding riders feeling a bit sketchy or nervous about pushing hard. That was not the case on the Sight VLT A2! We started pushing this bike hard from day 1. Sadly, that hard pushing caused a casualty after the second ride on our home trails. The RockShox Super Deluxe shock developed a bad noise and knock, which they pulled back from us to inspect and overnighted us a new unit – hence the Select+ model you’ll see in the images. We’ve had no issues on the new shock, and were very happy to have the bike ride troublefree ever since.
As mountain bikers first and foremost, the Norco Sight VLT A is a bike that stands out when it comes to mountain biking, especially when compared to the other Sub-$6,000 eMTBs. The geometry, stance, weight balance and overall demeanor of the bike inspired us to push hard, lean in and ride the bike the way we wanted to.
Our riders agreed that the bike excelled in a wide variety of terrain, but was especially capable on fast, steep terrain. It also enjoyed getting airborne, and never shied away from a chunky rock garden. In short, the Sight VLT A is versatile and really stands out among the recent crop of budget eMTBs.
HOW DID IT COMPARE?
Compared to the Amflow PR Carbon, the Norco Sight VLT A lacks technological refinements, power, and the buzz of the new Avinox drive unit. However, when it comes to attacking the trail, pushing hard and having a bike we feel comfortable charging the trail on, it’s a standout in the category. It rides quite a bit lighter than the Marin Alpine Trail E, and packs what many consider a more reliable drive unit system than the Canyon Spectral:ON. And the Norco frame comes with a lifetime warranty!
The Wolf’s Last Word
We can’t deny that the Bosch PX drive unit will likely be a deal breaker for many riders, however for our crew, the lifetime warranty, all-round capability and performance of the Norco Sight VLT Bosch A does not keep it off our list of bikes we’d buy with our own money. Norco have done a great job making an eMTB that has a competitive price tag but doesn’t ride like it. This thing is ready to shred, and we’re here for it.
WHO SHOULD BUY THE NORCO SIGHT VLT BOSCH A?
Someone who doesn’t need motor overrun to conquer their climbs, someone who likes a high RPM cadence, lifetime warranty and enjoys riding mountain bike trails. A rider who prioritizes suspension, geo and a robust frame over technology.
