First Look: 2023 Scott Lumen - The Electric Spark

Nov 25, 2022 at 9:18
by Seb Stott  

Scott have entered the race to build an ultra-light electric mountain bike. The Lumen is closely based on the Spark, the brand's XC/trail bike. It uses the innovative and lightweight TQ motor seen in Trek's Fuel EX-e, but Scott undercut Trek on the scales as their lightest model has a claimed weight of just 15.5 kg (34.2 lb).

The Lumen's other party piece is the ability to fit two water bottles or a bottle and a range extender battery inside the frame. Scott pitch the Lumen as "an e-bike for a mountain biker," with weight and handling much closer to a Spark than their other e-bikes and a serious focus on reducing noise to an absolute minimum.
Scott Lumen Details
• Claimed weight from 15.5 kg (34 lb)
• TQ HPR50 motor, 200% assistance, 50Nm
• 360 Wh battery + 160 Wh range extender
• 29" wheels, 130 mm travel F&R
• Headset cable routing
• Two bottles or bottle & range extender
• 77° seat angle, 65.5° +/-0.6° head angle
• Price: TBD

Motor & Battery

After considering alternatives from Fazua and others, Scott settled on TQ as the motor supplier for its low weight, noise, and ride feel. It provides 50 Nm of torque (that's 10 Nm less than Orbea's RS-tuned motor and 35 Nm less than a full-power ebike) and assistance goes up to 200% of rider input. That means if you pedal at 100 watts, the motor will add up to 200 watts.

There are three assistance modes to choose from, which Scott tunes to their liking, but these can be adjusted by the rider with an app.

The 360 Wh battery is fully integrated into the downtube - it's not designed to be removed easily. This helps Scott save weight by keeping the downtube structurally uncompromised. The optional 160 Wh range extender mounts to the downtube bottle bosses via a custom mount which can be swapped to a water bottle cage without tools. It plugs into the charging port just in front.

Anyone who's driven the Starship Enterprise should feel right at home with the Lumen's control panel.

Frame Details

The Lumen shares all the unique features of the Spark, including Scott's TwinLoc remote that firms up or locks out the fork and shock with an under-bar remote. Like all of Scott's recent bikes, the shock is hidden in the downtube, which Scott say is the most structurally efficient place to put it and leaves space for the two water bottle mounts in the main triangle. There's an extended air valve on the shock to make adjusting it more accessible and a sag indicator on the side of the frame.

Like the Spark, the Lumen also uses a flex-pivot rear suspension system to save weight, but it delivers 130 mm of travel to the Spark's 120 mm.

The top models use Scott's Fraser IC DC integrated cockpit. The standard top cap can be swapped out for an integrated computer mount.

The headset is the entry port for all the Lumen's cables. It's also an angle set, allowing +/- 0.6 degrees of adjustment.


The geometry is very similar to the Spark. The Lumen has a 12.5 mm longer chainstay length to fit around the motor and a slightly steeper seat angle. The head angle is similar in the neutral setting, but the headset cups offer 0.6 degrees of adjustment in either direction, from 64.9 to 66.1 degrees.

Models and specifications

There are four models in the range including the Contessa women's version (pictured above). Pricing is yet to be confirmed.

I don't need a lot of assistance so these lightweight ones are super appealing, but this one is a miss with that cable routing

 OK, I get E-bikes for Enduro and trail riding but Not sure why an XC bike needs an electric motor. next you are going to tell me they are going to make E-Road Bikes for all the Lycra wearing roadies... Oh Wait.......

 just wait till dangerholm gets his hands on one of these. watch out 27 lb ebike
  • 81 1
 Alright PB, essentially I have three options for this:
1. Build it super light to make it even more agile and simply push some limits.
2. Carefully fine tune it to shed some weight where possible but allow for some burly tires and brakes to make it super fun on the downhills while still being a breeze going up.
3. Build fewer bikes and do some god damn calf raises.
Let me know what you think!

 @dangerholm: lightest possible weight. If you don't strip that battery down to bare cells, resuspend them in nano-foam and swap the copper conductors for aluminium you aren't trying hard enough. If it catches fire during the process, count it as a win (just make like Bill Clinton and don't inhale the smoke).

Either that or do the @bicyclepubes collab as @BShaw suggests. I'd like one that recharges the battery from a hub dynamo, with an AXS seatpost dispensing bananas at the push of a button please.

 @Hobbanero: Option 2 doesn't make any sense. At that point you're trying to turn the bike into something it was clearly never meant to be. Spoiler alert, just because you stick on some aggressive tires, a Spark doesn't magically turn into a downhill bike.
  • 3 0
 @Muscovir: my experience with my Epic Evo is that the geo goes a long way in expanding a short travel bike's capabilities, but that brakes and tires then become the issue. The good news is that a tire swap can change the bike from an all day rolling epic focus to a short travel trail bike.

 wow, I was always wondering why Scott had these huge overzized downtubes... It all followed a plan, just like UDH
  • 27 4
 I was thinking the same thing, but it works. The bike looks good.
  • 44 30
 So Scotts plan apparently is to offer e-bikes that look similar to their mountainbikes. That way, their customers can really embrace their lazyness and buy an e-bike - but without the fear of being judged by mountainbikers.

 @SATN-XC: I actually thought I'd caught a guy sneaking an eeb into an illegal trail system the other day then realized it was a Spark.

But now I question myself.

You know, if people were so proud of their eebs, wouldn't the motor be a shiny, bling bit they'd be proud of showing off to everyone like guys with custom exhaust on motos????

The reason everyone is working so damn hard to hide the mopeds inside bicycles is so they can pretend they're doing the work & totally legal.

Just trying to feel less ashamed of being moped heroes. #allMyOldMtbHeroesRwhoringMopeds

 @blowmyfuse: I'm pretty sure riding an "illegal" bike on illegal trails makes it legal. You know, negative x negative = positive? I'm just always worried about getting caught on my analogue bike so I always ride with an ebiker, just in case.

On the real tho, if you "caught" someone riding on an unsanctioned trail with an ebike, even if you're the trail builder, you really don't get to complain - you're both breaking the law (cue Judas Priest) and that is, after all, the spirit of MTB.

  • 14 3
 Looks really good, but I think it needs more travel. 140-150mm rear and 150-160mm front is the sweet spot for trail bike in my opinion, but I guess that will be the Genius-version ebike.
  • 24 0
 Agree. I see no point for an e-bike to not have more travel. The benefits of shorter travel are completely negated by the fact there is a motor to assist
  • 12 1

 @SATN-XC: only somewhat disagree, just due to the added weight that more suspension adds. I like to bunny hop over rocks and ledges I encounter on my trails (uphill and down) and a lighter bike is easier to do so.
  • 1 1
 @motts: Yeah pedaling efficiency not needed on ebike, but Twinloc could be more about pedaling position because whenever you have the rear locked out climbing, it extends the rear shock and puts your body slightly forward which can aid in keeping both tires on the ground more evenly and the front not wandering as much.

 Love how none of the bikes with integrated routing show pics of it anymore, lest they get skewered in the comments.

Pinged the guys at my LBS - who is a Scott dealer - about routing. They hate building and working on headset routed bikes and basically echoed every negative point I've read in the comments. Only good thing they said was "maybe it looks slightly better... but bikes looked good enough to begin with." Nothing surprising here.

 you do adjust the air to adjust the sag, the indicator tells you what your sag level is, just like an o ring but because the shock is hidden in the frame, you can't use the o ring method.

 @gonzocycle: Watch the above video. Scott calls it a "sag adjuster" and there is a port to access it. There is no reason to have a port in the frame for just the sag percentage indicator.

 @tacklingdummy: the port is where you access the shock to adjust the air.
  • 1 1
 @tacklingdummy: the port shown in the video is to access the shock bolt, for removing the shock for servicing. It has nothing to do with the sag. They show it so you can see the shock moving inside the frame. Air goes through the window in the bottom of the downtube.
  • 1 1
 @gonzocycle: They would not call it "sag adjuster" if it was just for the shock bolt.

 @tacklingdummy: OMG man, you are thinking too hard. Watch this from the normal spark. @ 3:36
  • 1 3
 @gonzocycle: It is very misleading and used the wrong wording if you are right. They should have used "sag indicator" like they did in the Scott Spark video. Scott bikes are very precise with their products and marketing, which is why I don't think they would use the term sag adjuster loosely.

 I thought like that for 20 years mountain biking when healthy with no injuries, but when I got older and got some overuse knee injuries, I totally see the value in ebikes. The fact is that every hardcore PB mountain biker will get an ebike when they get older because they want to extend their riding rather than not ride.
