Question about using Levociraptor on 2022 Levo Alloy Comp

[Shooter88]

I have a 2022 Levo Alloy Comp and want to install a Gen 1 levociraptor on it. My goal is to de-restrict the bike to get a class 3 pedal assist of 27 MPH or maybe 36 MPH, (selector 4 on the unit). I wouldn't need pedal assist above that. I will not be using BLevo or need any of the features of the Gen 2 or 3 units. My concern is, after installation, does the computer still record mileage ridden correctly in the Mastermind phone app? I have the blue LED TCU on the bike that only shows battery level and power level. I'd like to be sure the miles ridden is still being recorded correctly in the phone mastermind app. Does anyone have any experience using the Gen 1 unit on a Specialized Levo?
Thanks.

You confuse several things, I think. From your description it looks your Levo has the Gen 1 TCU. The app is called Specialized (new) or Mission Control (old). Mastermind is the name for the Gen 2 TCU display. Having said the above, I can bet the Levociraptor would report wrong speed and distance ridden in either app. (That's why BLEvo is used as the app, as it can artificially make up for the Levociraptor "cheating" the motor and the controller).

On the other hand, are you sure you want to derestrict your Levo? With the tiny chainring of the Levo you would need to pedal at superhuman cadence to get at even 27 mph... (E-MTBs have never been designed for speed but for climbing and riding technical singletracks).

I have a 2022 Levo Alloy Comp as well. I am using Levociraptor Gen 3. I don't understand your question so wouldn't be able to answer, but I just want to point out something critical if you intend to use Gen 3 on your Levo.

The Gen 3 cannot fit into the top tube chamber on the alloy Levo (no problem with the Carbon Levo) because there is not enough space. The internals are just constructed differently between the Carbon and Alloy Levo.

You will need to remove the Gen 3 chip's casing and use some heat wrap to waterproof the PCB board (something like the Gen 2) to make the whole chip's dimension thinner and this will then fit onto the Alloy Levo.

Here is a cut & paste from another site about my question;

My challenge is this, I have both a '22 Levo comp, (class 1), and a '23 Tero, (class 3) and I ride them everywhere. I really like the Tero 27 mph assist on the street but I ride alot of single track and it is not as capable there as the Levo. If I could get the Levo to a 27+ mph pedal assist and have it pedal like the Tero, I'd sell the Tero.
I want the suspension, brakes and handling of the Levo but the motor/pedal assist performance of the Tero so I can consolidate two bikes into one.

FWIW, my Tero 4x ,(50NM motor), has a 38T ring on it and I can hold a comfortable 25 mph speed on flat asphalt with it in top gear. The Levo has a 32T ring on it and you can tell when the 20 mph threshhold kicks in and the party shuts down. I cannot even use top gear on the Levo. I wonder what a 38T ring on the Levo would do?
Please post if you put a 36T on your bike and how it works out as I'm very interested. I have not priced a 36T but in comparison to the cost of the bike it couldn't be that bad??? Thanks again.

Voodoo, are you still using the stock 32 T chain ring? If so, what are your impressions of it with the Raptor installed. A guy on another site said Levociraptor suggested he go with the 36T sprocket when using the raptor?? Your thoughts?

 

[Shooter88]

I also found this data; "All Levo models use a 12 speed drivetrain with a single front chainring. 32t minimum and 34t maximum (with chainguide) or 36t maximum (without chainguide). It appears in order to use a 36 as Levociraptor suggests, you would need to remove the chain guide. I wonder how the 34T would impact the pedal characteristics?

 

[Stefan Mikes]

I wonder what a 38T ring on the Levo would do?

If you could fit it You know you cannot.

Besides, what is the cadence you need to muster to ride 27 mph on the Tero with the 38T chainring? Then think of the necessary cadence with the 34T chainring...

Shooter88, I have a Turbo Levo Comp (2022 model) and I have fitted a velociraptor (Gen 2) - it installs in no time and there was no issue with enough room to poke it into the top tube. Took about 2 mins to install completely. Works perfectly - I don't really need it while MTB'ing but sometimes it's good to be able to exceed 25kph on the way home or when joining a gravel ride.

Creo, 25 kph is only 15.5 mph. The Levo is a class 1 bike and here in the U.S. it has pedal assist to 20 mph which is 32kph. Does your bike have assist to 32kph, (20mph)? I'm wanting to increase my pedal assist to a class 3, 27+ mph, (43 kph), does the Levociraptor do that on your bike?
Thanks.

Shooter88, in Australia (and I believe Europe) ALL ebikes are limited to 25kph (there is no Class 1, 2 3 etc). With the Levociraptor you can set the assist speed from a range of choices - 41kph, 57kph (the default) and 72kph. So yes, the Levociraptor does exactly what you are looking for - with the default setting will provide assistance up to 57kph (35mph).

Thanks for that reply. What do you have your default set at? On a smooth flat paved surface, is it possible to maintain for a short period a 40kph, (25mph) or a short burst up to a 48kph, (30mph)? I ask this as I've seen some people say the front chain ring sprocket size on the Levo's may make attaining these speeds difficult.
Thanks.

On the Levo I leave the default setting at 57kph - more than enough (I use the same setting on my Creo roadie for that matter). Using a gear calculator, and noting the Levo has a 32 chain ring and a 10-52 cassette, in the big gear you would need a cadence of 90 to achieve 40kph (powered, not downhill obviously). A cadence of 110 gives 50kph. I have taken my Levo on a couple of rides on the road with my mates on their (non-e) road bikes, and had no trouble keeping up. The Levociraptor is absolutely needed on the Creo (if you're in a '25kph region'), and while not absolutely necessary, I do like it on the Levo for the odd occasion when I want to go faster than 25kph. I've had zero issues with both Levociraptors - of course the Specialized apps record only half the speed and distance, but I rely on my garmin edge for the correct readings, and also connect to the bike via Ant plus for power, cadence etc. All works pretty well

Creo, that cadence info is good to know, thanks very much for the reply.
