Levo Gen 4 Specialized Gen 4 Levo - Official Thread

it’s a quite heavy bike compared to previous generation but at list tyres should be main impact (grid trail to grid gravity). I really would love a SL with 480wh built-in battery…

I'm with you. The 50Nm needs a boost to keep up with the competition. I think 60-65Nm will be the new normal for <45 lbs bikes. We'll see what happens.

The biggest flaw of the implementation is that every buyer is forced to buy the 840wh battery. Even light/fit riders or people who only have not much elevation/time.

If the 600wh would be optional with a discount for first buyers the bike would be considerably lighter and overall a more competitive package.
I disagree. I have have almost 175 miles on Levo 4 sworks and it burns the battery quick! I think if it came out with the 600wh battery in it there would be a lot of complaints about range.

For example I have 2 miles of road to get to my trailhead, its rolling with gradual climbs and in class 3 mode with turbo it uses 10% of the battery in those 2 miles.

The same 16 mile loop I used ride my Levo 3 alloy and it would use about 30% of the 700wh battery in Turbo (I would actually go two rides without charging). The Levo 4 uses 50% of the 840wh battery in turbo on the exact same loop (auto mode wasn't really any different). The difference is that my average speed is 1 mph faster on the Levo 4 over the whole ride.

I figured out now with the Levo 4 that I need to shift to eco mode on level trails and downhills to preserve the battery as with the Levo 3 I could just leave it in trail or turbo mode and not worry about the battery.

I was thinking I would get the 600w battery but now I don't think it's big enough if you are going to want to ride over an hour in anything above eco mode. I feel bad for the guys buying the alloy with the 600wh battery stock.

But you would still have that horrible looking down tube, it looks shockingly bad imo. After 7 high end Levos over past 7 years this is what makes it a none starter for me.

Interesting,
I also have a couple of miles of road ride to get to my trail on the AMflow, combined my loop is 16.7 miles. Yesterday I used, turbo, boost, trail, and auto modes. After the 16.7 miles when I arrived back home I had 54% batt remaining.
 
For example I have 2 miles of road to get to my trailhead, its rolling with gradual climbs and in class 3 mode with turbo it uses 10% of the battery in those 2 miles.
That seems like a crazy use of power from my experiences, going to test this tonight (Class3/turbo). This past weekend I rode 25+ miles with a combo of class3/turbo/trail and had 35% left and felt I could easily run this bike 40 miles with 3000ft + climbing. Do you have Shuttle on?

Well, there are people that only use turbo on technical uphill sections like me. I never used close to fully power settings on an ebike.

My local trailheads are all too far away so I always have to drive there with a car/campervan anyway which means I don't have much scenarios where I have to quickly get to the top. I usually just get into a steep fireroad climb with a mix of downtuned eco/trail on the gen3. Plus being light full power turbo is overkill for me anyway. It would throw me from the bike in steep sections or uphill hairpins.

I also carry my ebike in alpine terrain which is why weight is important to me.

I will check I don't know. I have turned off/down overrun so it's more natural pedaling.

A few days ago I did 27.83 miles with 3,176 feet of climbing in mostly auto (there was about 8 miles of flat road in class 3) and I burned 100% of the battery. I probably ran eco for a few miles when I saw the battery getting low.

Was this all in Turbo (minus the eco you mentioned)?

I would be interested to see if you set your Levo 4 to 80% peak power and 100 support (to simulate the gen3) what the range would be .... that will give you an indication if the new motor is more efficient or not ?

Correct Auto regular mode (not + or -) with overrun turned off.
Well I just slammed that bike 2 miles (on rolling hills) in class3 & Turbo and could only burn 6%, did it two times with same results. I did not have it in shuttle but the option to put in in shuttle is there but not sure if that even works in class3 or if it burns more juice than turbo. Obviously I would need top ride the same route as you for a 1 to 1 but 4 % more seems like a lot. I even rode the hill a 3rd time on the second pass and managed to burn 8% in 3 miles, and basically 2 of those miles were up a hill.
 
Im in the se boat as you, going to keep sending it on the gen 3 for now, it still kicks ass. What's a boost battery and flush plug? A range extender?
Here in SD the bike shop that I checked out the new Gen4 last week said I better buy now as when the tariff kick in the price would increase 10%.
Im standing pat with my Gen 3 as it’s set up for what I want and don’t see any benefit in trying to sell mine and then having to do the same to a new bike.
Fox 38, Cascade long travel link, carbon wheelset, carbon bars, 220 rotors, spank pedals, deristrictor, boost battery and flush mount plug, spank seat, Maxxis tires, you get the idea.
 
Yeah a boost battery is one I picked up from Graham at Trailwatts in the UK.
They come with the cord connection that requires you to "notch" the plastic motor housing to connect up to the water bottle style 280w extender battery but I mounted a flush plug on the frame for a cleaner look.

Mo beta...
 
So far so good, 1 week with the G4 Expert, 133km. Today tried to find what is the range riding really fast, got many PBs on Strava.

The estimate assistance was:
- 20% eco (50/80)
- 75% trail (75/100)
- 5% turbo (100/100)

Trip:
- 33 km
- 845 m
- estimated range left 7 km
- 22% battery left

Configuration:
- Power: Pre set FAST settings (eco 50/80, trail 75/100, turbo 100/100)
- Shuttle on MAX
- Auto+

Here is my screen shot from Strava it was actually from 0 to 2.3 miles that I burn 10% battery. The grade is average 5% and it is on road. I weight 218lbs and I am in average condition.

Nice!

What is your weight and general fitness condition?

Thanks a lot for sharing!!!

The fact that you have in all modes a pretty high assistance confirms me that I would not need the 800wh battery 😆

Super clean look. Hopefully a crack doesn't start from the new hole. Did you reinforce or just drill a hole?

Agreed those are pretty high assistance settings , for reference my are:
- eco (35/35)
- trail (50/100)
- turbo (100/100)

and I ride between eco and trail

well I weigh 180 Lbs and on a S-3, but the ride profile looks pretty similar. Regardless, I agree the bike can eat more juice than the g3. As I stated in another post this bike has a tons of power and if I get on hills (fire roads) that 15% or > I can sustain continuous 1000watts and tank drains pretty fast. So if you are maxing this motor then I wouldn't expect max range :)
 
I use mine a little different.

25/45
45/80
60/80
and then u use dynamic microtone if I need more than that, that way I get a nice broad setting
I mean its going to come down to fitness, and my trail (50/100) setting is overkill for any thing I have encountered. So I will be micro tuning once I get back from vacation. 35/35 eco really lets you feel the bikes weight when steep climbing.
 
When I dropped the motor I looked up inside the seat tube area it looked pretty well inforced.
There is actually a small cut out with a plastic plug on the lower backside of the same seat tube, what that is for I’m not sure.
The opening I made is basically filled up with the hard plastic/rubber xt60 plug.
Been like 10 months and no worry’s so far.

Would be nice if this extender battery worked on its own like the newer gen4 one.
That way I could possibly have the options of 252w, 500w, 700w, 752w, or 952w.
Maybe next version if TW ever does any mods.
We’ll see.
