We not too long ago took supply of the street-legal Alta Redshift EX and put it within the fingers of a number of take a look at riders of various ages from 26 to 62 and talent ranges starting from novice to professional. Many of the take a look at riders had by no means ridden an electrical bike earlier than, however the one factor all of them had in widespread was they listed the Alta as “a enjoyable bike to journey.” Using an electrical bike delivers an expertise that’s considerably completely different than driving a gas-powered bike, and it’s a constructive sensation—one which saved every take a look at rider who didn’t have the luxurious of maintaining the Redshift EX of their storage craving to have it of their possession. We examined the Redshift EX on every little thing from the road to tight technical trails to the motocross observe and had been happy with how nicely the bike carried out in every space and its general versatility.
The engine is certainly the most important distinction on the Alta compared to a gas-powered machine. The very first thing that jumps out while you get on the bike is the absence of a clutch and shift lever. Not shifting by way of gears is a novel sensation at first, however as Alta’s newly signed EnduroCross racer Ty Tremaine identified in a current interview we did with him, “You’re basically in first gear and fifth gear the entire time.”
The Redshift EX has 4 preprogrammed maps that may be accessed on the fly through a module positioned on the left facet of the handlebar. No matter what map you’re in, the bike requires roughly one-eighth of a flip of the throttle earlier than it begins to maneuver, which is definitely similar to how a lot throttle you’d give a gas-powered bike whereas slipping the clutch to get it shifting with out stalling. Every map provides an identical energy curve, however with rising quantities of energy and hit, particularly because the rpm enhance.
Map one is right when driving at decrease speeds corresponding to tight and technical single-track. It’s just like first or second gear on a gas-powered bike, however with the flexibility to be ridden at decrease speeds with out slipping the clutch excessively to forestall the rear wheel from spinning and/or the bike from stalling. Map one is the place the Redshift EX’s unbelievable potential to keep up traction is most noticeable. Whereas driving over rocks and different obstacles, the Alta can creep to a close to halt and nonetheless hold the rear wheel monitoring. Simply while you suppose the rear wheel would possibly break unfastened and begin spinning, the bike continues to trace ahead and hook up.
Map two is pretty near map one when it comes to energy and torque, and accordingly works nicely in lower-speed conditions. It mimics map one’s wonderful potential to realize and preserve traction, however has a faster and harder-hitting throttle response and works higher when the path opens up and the speeds enhance barely. Map three is the perfect all-around map for any driving that entails speeds greater than tight and technical single-track. Map three can deal with nearly every little thing and take a look at riders agreed it supplied the perfect stability between hard-hitting energy and lack of wheelspin. Map 4 provides essentially the most energy and might catch you off guard if you happen to seize a handful as a consequence of how hard-hitting and snappy it’s. Map 4 is so highly effective in reality that it will probably break the rear wheel unfastened noticeably simpler than maps one by way of three when driving the Alta on any sort of terrain apart from asphalt. Map 4 remains to be helpful on the dust; it simply requires a bit extra discretion of the throttle hand and works finest when driving at a quicker, extra constant pace. When driving in map 4 on the road, we obtained the Alta as much as 86 mph based on the on-board speedometer.
So far as engine-braking goes, the Alta falls someplace between a two-stroke and a four-stroke, however barely extra towards a four-stroke. When off-throttle, the bike’s engine-braking is gradual and predictable, which helps make the transition from driving a gas-powered bike to the Redshift EX that a lot simpler. So far as battery life on the Alta goes, we had been in a position to squeeze simply over an hour of faster-paced off-road and path driving. When the battery is totally useless, it takes roughly 4 hours till it’s absolutely recharged.
The Redshift EX is spec’d with a WP 4CS fork and WP shock. Each ends are understandably valved and sprung on the softer facet to accommodate the kind of enduro driving the bike is designed for. The 4CS fork does a superb job of absorbing small impacts corresponding to rocks or some other sort of minor impediment one would possibly encounter on the path. The entrance finish stays nicely related to the bottom and garners wonderful traction consequently. The 4CS unit does sometimes backside out on bigger impacts corresponding to when leaping to flat and on medium-sized drop-offs, however that’s to be anticipated seeing because it’s set as much as be extra of an all-around, do-it-all enduro bike.
The WP shock is a bit softer than the fork and does an outstanding job of serving to the rear wheel garner the traction the electric-powered engine supplies. The suspension labored nicely on the road in addition to the paths we took it on, and we couldn’t resist taking the bike on the vet observe at Cahuilla Creek MX on our first day trip with it. Whereas the shock was understandably a bit mushy for a motocross observe, we had been happy to seek out that the suspension labored nicely on the tabletop-jump-filled format and dealt with landings simply high quality. The suspension works nice on the terrain it’s designed to be ridden on, however it will probably maintain its personal on absolutely anything you possibly can throw it at.
The Redshift EX chassis does a number of issues very nicely. First, the bike is extremely simple to stability. For instance, when driving on a decent, technical path at very sluggish pace, it’s simple to maintain your toes up and proceed motoring alongside. The bike additionally has nice straight-line stability and is predictable at greater speeds. More often than not, straight-line stability and cornering potential are trade-offs, however such is just not the case with the Alta. We particularly seen this when driving the bike on the vet observe at Cahuilla. The bike dives into corners very simply, making sudden line modifications practically easy. Whereas the bike is nice at lean in, it additionally stays planted and stays predictable all through the whole lot of the nook as nicely. Whereas the Alta chassis feels mild and nimble on the bottom, some take a look at riders famous that it feels a bit heavier as soon as airborne, however acknowledged that it wasn’t main and the way in which it dealt with on the bottom far outweighed the way it felt to them within the air.
Conclusion The Alta Redshift EX is a blast to journey. All of our take a look at riders who obtained the chance to journey it loved ripping round on the Redshift EX no matter what pace they had been going or what terrain they had been driving on. With a quiet, torquey, and quick electric-powered engine, compliant and versatile WP suspension, and a chassis that has a noteworthy mixture of fine cornering potential, confidence-inspiring straight-line stability, and ease of stability when driving at sluggish speeds. We stay up for driving the Alta much more because the yr progresses, and with no oil to alter or air filters to scrub, essentially the most tough a part of having this bike would possibly simply be deciding which take a look at rider will get to have it as their Lengthy Haul bike as there are many prepared and keen candidates lined up for the job.
