Popping the entrance on the Bullit is difficult due to its weight and lengthy chainstays.
Ian Linton / Fast Media

I took to the paths in Scotland’s Tweed Valley to check out the brand-new Bullit, aiming to combine old-school DH tracks with the famously tight and choosy off-piste strains in a bunch of circumstances.

Under are my findings after in depth testing.

Due to the unbelievable Fox 38 fork and RockShox SuperDeluxe Final air-sprung rear shock, the Bullit was simple to arrange. I put 95psi within the forks and set the low-speed compression damping to -12 clicks of a possible 16 from closed. I left the high-speed compression absolutely open and set the rebound to style.

I set the rear shock to 27 per cent – equating to roughly 180psi within the air spring – and left the low-speed compression absolutely open and adjusted the rebound to style.

Utilizing Shimano’s E-TUBE app, I adjusted every of the EP8 motor’s assistant modes – Eco, Path and Enhance – to take a seat at their most ranges of help.

I inflated the entrance tyre to 25psi and the rear to 28psi and took to the paths.

2021 Santa Cruz Bullit CC X01 RSV climbing efficiency

The Bullit’s geometry made climbing a problem to relish.
Ian Linton / Fast Media

The Bullit’s climbing efficiency immediately impressed me, providing copious quantities of management and grip.

Its capability to scale climbs usually too tough or steep to deal with wasn’t only a product of anyone particular a part of its spec, geometry or suspension relatively a end result of all components of the bike coming collectively cohesively.

First up, the lengthy 449mm chainstays, when mixed with the 1,268mm wheelbase and 848mm entrance centre, meant my weight was extra central on the bike compared to others with shorter chainstays.

This helped me hold the entrance wheel on the bottom without having to shift my whole physique in direction of the entrance of the bike.

Whether or not out of the saddle or sitting down, the Bullit was simple to level uphill.

And since I wasn’t having to maneuver my weight to this point forwards to keep up higher management of the entrance wheel, I used to be capable of deal with getting the utmost quantity of grip out of the again wheel whereas sticking to my chosen line.

I additionally discovered Eco mode on Shimano’s EP8 motor – when arrange with its highest quantity of help within the E-TUBE app – supplied essentially the most management below energy, making it simple to keep up rear wheel traction even over slick roots and rocks on significantly concerned climbs.

In comparison with Enhance mode, I did should work tougher ascending in Eco, however discovered the improved grip and management was definitely worth the elevated effort.

The bike’s ascending prowess was additional improved by its suspension. Though it bobbed a good quantity below energy, particularly when standing up pedalling (though this arguably isn’t a difficulty with an electrical mountain bike), it was easy and supple over small and medium bumps, so the rear wheel conformed to the bottom and supplied each consolation and traction.

Consolation is vital on an electrical mountain bike as a result of tough ascents and flatter traverses are normally tackled seated. Though the Bullit’s suspension excels right here, its geometry did put me in a extra aggressive forward-leaning place on flatter sections than I might have preferred, which prompted fatigue as extra of my weight was put by my arms.

The next rise bar or extra stem stackers below the stem might assist scale back this drawback on flatter sections, however might affect climbing efficiency.

The DoubleDown Maxxis DHRII 2.4in huge rear tyre was a very good match to the extra forces delivered by the electrical motor and weight, and the MaxxTerra compound actually helped additional enhance its climbing prowess.

Technical, rock-strewn ascents had been dispatched with ease.
Ian Linton / Fast Media

I didn’t discover the saddle significantly comfy. Its rounded form with a excessive central level focussed stress on my perineum relatively than my sit bones. It might be good to have the choice to spec a saddle of selection on the level of sale, particularly on a motorbike that prices this a lot.

Totally charged, the 630Wh battery ridden completely in Eco mode had a 57.31km, 1,755m ascent vary till it entered its battery-saving limited-assistance characteristic. These figures are merely a information and totally different circumstances and riders will possible produce totally different outcomes.

General, I completely cherished climbing on the Bullit and located it remodeled arduous climbs into technical challenges to be relished.

2021 Santa Cruz Bullit CC X01 RSV descending efficiency

The Bullit’s at dwelling charging on tough terrain.
Ian Linton / Fast Media

On the descents the Bullit didn’t disguise its 21.25kg weight properly, however then it didn’t have to. Over tough, quick and gnarly terrain it ploughed by obstacles and caught to strains whereas carrying pace the place a whole lot of different bikes would have faltered.

The suspension’s suppleness not solely helped on the climbs, but in addition did a sterling job of smoothing out tough trails with whole proficiency. Rock gardens or root-strewn cambers had been absorbed and numbed down impressively, serving to me to focus on driving the road I needed to.

I discovered the easiest way to journey the Bullit was to level it the place I needed to go and let it take care of the terrain beneath me, its suspension, weight and geometry combining to create a remarkably calm journey.

The suspension was additionally impressively well-equipped to take care of greater hits like massive drops and flat or g-outs. It felt like there was ample development tuned into the suspension’s kinematic, complemented by the pure ramp up of the shock’s air spring.

Fortunately, the Fox 38 fork was properly outfitted to take care of the additional weight of the battery and motor.
Ian Linton / Fast Media

As soon as the paths obtained a little bit slower its weight was tougher to handle and it took a whole lot of deliberate man dealing with to get it pointing the place I needed. Making on-the-spot line selections on trails that I didn’t know was tough.

On lighter bikes it might be potential to flick between strains on the final minute, however the Bullit required extra dedication earlier on, limiting my capability to flit between strains.

Though the Bullit is likely one of the slackest long-travel electrical mountain bikes on the market, contemplating how briskly and onerous it may be ridden I felt like the top angle may very well be slacker. This is able to enhance its manner on steeper trails with none detrimental results on efficiency elsewhere.

Fox’s 38 fork is an ideal accomplice for the Bullit’s tempo and capabilities.
Ian Linton / Fast Media

On steeper descents, and particularly once I was on the brakes, I might really feel the bike’s weight driving into the entrance wheel, overwhelming the entrance finish and inflicting twitchiness.

The Fox 38’s damping and chassis did a outstanding job of controlling the load shift, however the best way the bike behaved as soon as it obtained very steep left me wishing for a slacker head-tube angle.

General the geometry was properly balanced, and I discovered I might assault corners and straights confidently from the get-go. The 475mm attain meant there was loads of area when standing up and, in addition to the bike’s weight, helped scale back the results of faulty rider inputs.

Leaning over in turns required loads of dedication.
Ian Linton / Fast Media

I discovered the SRAM Code RSC brakes – with a 220mm entrance rotor and 200mm rear – began to fade and lose their chunk on extended descents when ridden aggressively.

Codes are a few of the strongest and standard brakes available on the market, so having a motorbike that may push them to their limits is not any imply feat. It might be good to see 220mm rotors fitted each entrance and rear, or a special set of brakes with extra energy specced from the manufacturing facility.

The Code brakes had been overwhelmed by the pace the Bullit might obtain.
Ian Linton / Fast Media

Elsewhere, I discovered the dropper put up prolonged to the proper climbing place and dropped far sufficient – however solely simply – to be out of the best way on the descents for my preferences.

I additionally had no complaints concerning the carbon fibre Reserve wheels feeling too stiff or flexing below the load and speeds the Bullit allowed me to hit.

As a bonus, they resisted dings and flat-spots even after bottoming out the tyre, inflicting the rim to hit a number of rocks. Likewise, the Maxxis DoubleDown tyres fitted to each the entrance and rear didn’t puncture or tear through the testing interval.

I additionally felt Santa Cruz’s Di2 bar was comfy and I didn’t discover any undue harshness transferring into my arms on tough descents.

Establishing early was key to driving the Bullit properly when the paths had been tight.
Ian Linton / Fast Media

It was the Bullit’s climbing prowess that impressed me essentially the most. Pointing uphill, it simply felt unstoppable because it gripped to the path nearly no matter circumstances, and the EP8 motor supplied extremely controllable help.

The massive 630Wh battery and adequately powered Eco mode mixed to offer almost 60km of vary with 1,755mm of climbing, and made all-day epics with out battery nervousness a actuality.

On the descents there was no denying simply how succesful the Bullit is, significantly when tackling sooner and rougher trails because it ironed out chatter and held strains that may make lesser bike wince.

Slower, tighter and steeper bits of path wanted to be taken with much less gusto, although, and some geometry tweaks ought to enhance its low-speed manners.
