UPDATE: Stopped by shop to see if they had the bolt. Main guy, super confident, tells me it doesn’t make sense, because he personally tightened the bolt. (This sums up most of our arguments; hyper confident replies without listening/thinking) so I tell him how the only thing holding the battery on was the janky skid plate, and I’d hoped the bolt would have stayed sandwiched up in there, but didn’t find it.
Then he goes big eyed, backpedals, heads back into shop. Comes back with the bolt and a $25 gift card.
I promptly buy $26 worth of stuff, then circle back right before closing with $25 worth of cold beers. Balance restored to the universe.

Well played. Props to spesh too. If you get another 4 it probably doesnt owe you a penny

Repeater vs Relay PNW

49.1lb Repeater Full power Shimano E8 85nm/500W 29er 160/160 with built in 630wh battery and an X2
vs
45.5lb Relay PNW Medium power Fauza 60nm/450W MX 170/170 with swappable 430wh battery and a DHX coil (flip chip turns it into a full 29 170/160)

[XXX-er]

If its anything like my 52 lb Bullit with 630W/ EP8 which has a 49 lb advertised weight Its probably 52 lbs but 49 sounds better than 52, either way you will get used to muscling the weight around and personaly I don't worry about weight with 85nm of power

I would go with the Shimano's Ep8 motor & 630 battery ( or bigger ) the EP8 battery easily swaps out with 1/4 turn of the battery latch, IME this combo is good for about 4 or 5 hrs in boost mode at the bike area by which time i am ready for a beer

Not famiiar with Fauza but i would go with a bigger battery & a stronger motor, I don't see any point in a lite version of an E-bike

I DO like the 29/ 27.5 mullet desgn at least on the SC product

Cool that the Shimano battery is easily swappable. I imagined when I bought my Levo that I could swap batteries easily and maybe get a second one for longer rides, but they are tough to swap in the field, as the system is very sensitive to any dirt. Do any other motors have easily swappable batteries?

[XXX-er]

Duno but Norco has the option of a 540Wh, 720Wh or massive, industry-leading 900Wh shimano battery

https://www.norco.com/bikes/e-mounta...ain/sight-vlt/

The batteries got up to 630 in I believe 2021 which is pretty good for my purposes, you could carry a second battery, its as easy to change as poking an allen key thru a hole and turning a latch which seems like an allen fastenr but its really just the head of a 1/4 turn latch so don't reef on it, I think any bike running the Shimano Ep8 will have easily an easily swapped battery

I had similar thoughts on wanting the extra range.

My mistake the PNW is 45.5lbs vs the Repeaters 49.1lbs. That is a much more significant weight difference, pretty much explained by the 2.5lbs of battery, 0.6lbs of motor, and 29er extra on the Relay, and another pound somewhere on the Relay as the PNW has the coil. Pretty strong argument fort the Relay PNW being 29 convertable, 40.5lbs without the batter and can be ridden without the battery. 60nm and 450w would be enough for me with the hot swappable 5# battery. I found 35nm, 250W, and 360wh (w extender) on the Kenevo SL anemic...

Super strong arguments for the Relay PNW...

Except the Repeater is on sale for 17% cheaper than the Relay PNW for the comparable builds... kinda hard to say no to that.

[Benneke10]

XXX, I may be misunderstanding your post, are you saying that you get 4-5 hrs of riding across one battery or two? I can usually burn my 700wh battery in 2-2.5 hrs using turbo, or longer if there is hike-a-bike

[MegaStoke]

I get approximately 10ft of vert per watt hour on my Giant Trance, and saw similar range when I demoed an Orbea Wild. This is climbing fire road, pedaling 150- 200 watts myself, medium assist, and me weighing 160lbs.

[XXX-er]

yeah I'm 165lb so one 630W battery will do me 4 hrs of pin-balling around the local area in boost for sure, 5 hrs may be pushing it,

unless the battery didnt charge cuz i fucked up I always charge between rides so I don't think i have run the battery flat in one ride, range has not been an issue with a 630W battery for my app

[XXX-er]

You should check into it further but its my understanding that the lite versions of these E-bikes like maybe the Orbea are STILL using the EP8 motor which still weighs > 6 lbs they just dummy it down with the software to give less nm's of power and use lighter batteries with less power capacity

The E-bike hater will still hate you as much as if you bought a full powered E -bike so I don't get it

How much vertical are you getting in that amount of time? I can get 4500-6500 ft in turbo mode depending on the terrain on my 700wh turbo levo (I'm 150lbs). I was kinda hoping for a little more, some friends can get more but they are fitter than me and are consistently putting out more leg power than I can manage

[XXX-er]

not really that sure what the vert is, its maybe 3 times up the area and riding back down all of it in boost but there are so many switchbacks and turns that i've done 3000kms in just under 2 seasons at an average speed of 12kph

[skinipenem]

I can't add useful details for the Decoy since usually only ride for a couple hours, then I'm bored and go home. Unless I'm riding the park on the decor instead of dh bike, then I ride until I have to go home; however, minimal battery is used. I think there are a number of variables in play when it comes to battery life: temperature, cadence, speed, rider input, vertical ascent, acceleration, mode choices.

I can say that the mullet setup is very nice. I think it unnoticed the handing of the heavier bike.

Battery life comes down to how long of rides you are planning and if those rides will loop by your car for a battery swap.

If you plan to do long ride get a big ass battery or a booster.

That roughly lines up with my levo. I only have the 500wh battery, and I can get around 5k vert in trail mode.

I do find that my battery usage is strongly tied to speed. Quickest way to kill a battery is to go fast up a dirt road climb. Slow single track climbing uses a lot less juice for me. Which also makes xxx's numbers seem plausible since he says he's only averaging 12 kph.

I've only had my levo for a few months but so far for me, the opposite is true. If I'm climbing consistently steep dirt roads I can get the most vert out of the battery. I get a lot less with switchbacky or rough trails that require more changes in climbing speed.

It wouldn't surprise if this just came down to the rider. At least for me, on dirt roads I'm going a speed that's pretty close to where the motor cuts out (20-ish mph), and the motor is doing a lot of the work. Whereas on trails, I'm going nowhere near the max class 1 speed and I'm putting a good bit more effort into the pedaling.

I certainly could put more effort in on roads, but if I wanted to work hard, I wouldn't be riding the ebike.

[Benneke10]

I'm talking more about steep dirt roads over 10% grade, like ski resort service roads or OHV trails, routes that see very little bike traffic because they are too steep or loose. That is the perfect ebike climbing terrain for me, don't have to feel bad about passing other riders and its efficient.

[XXX-er]

There is one road thru the entire area it good for getting a 4x4 up on trail work but nobody rides it, i'm not sure how much of the area is machine built but there are 180 degree switchbacks thru-out the area, there is more than one spot with 1/2 a doz bermed switchbacks and so its impossible to go very fast or get into top gear on the trails, I could use more power but not more speed , thats how I put up a stat of 3000kms at < 13kph

Usually I drive to the area but last week I rode there behind the golf course down by the river, some easy trails around town and on the road it was no problem to max out the EP8 at 32kph

but lots of squiggles on the bluff, its really a very small area packed with single track

There are groups of boys around here riding Talaria’s and Siron’s around as E Bikes. When does an E Bike become a motorcycle? This is not a rant, just a question. Those things are faster and more powerful than some of the old motorcycles I raced as a kid.

Those things are just electric dirt bikes. They're not limited in any of the ways that would slot them into the ebike class 1/2/3 categories.

When it has a throttle it is a crossover moto. When it is has no pedals, it is unequivocally an e moto.

Type 1 ebikes are pedal assist and stop assisting the pedalling at 20kph.

Sur-ron Xs and Light Bees have a throttle, no pedals, and are governed at 80kph. That makes it an e dirt bike. They also weigh about 100lbs.

[XXX-er]

Goggle Pedelec standard,

a class 1 E-bike should have a < 500W motor with pedals that work

Riding a Suron on the road there are all kinds of issues with trying to pass off an electric scooter as an E-bike that will get you 600$ of tickets from the law

these bikes and scooters don't have registration so you can't insure them even if you wanted to go legit

[Canada1]

They’re riding them on the paved paths and sidewalks. I’m sure their parents are looking at them just like the hordes of kids on other e bikes. Heck, they are attractive as a parent because all of the sudden your kid can get themselves to practice, school, friend across town, etc. I just have been surprised by getting passed by kids on these big ones. They have more suspension than the YZ 80 or 125 I was motocrossing on years ago. Probably something the sheriff doesn’t want to deal with, but will be forced to before long. True first world problems.
