Wondering why Santa Cruz etc are releasing bikes in 2020 with an 'old' motors?

This new one coming out this year. It'll be backwards compatibles.

The new Shimano EP8 motor will fit into your old Shimano E8000 holes.

The point is surely that it is new info that many people may be interested in before deciding to buy a new bike?

If they had waited they would have missed out on 8/9 months of sales, when ebikes market is rising as it is, thats probably alot of money to them.

Like you said tho, it fits in the e8000 hole, so you can upgrade later down the line if you want - where is the proof on this tho?

You could waste your entire life waiting for the next version of most tech.
That to me is a mistake. We're only here for a very short time.

I think on lower price point bikes its not a big deal. If I was planning on dropping £10k on a santa cruz for it to be "out dated" within 12 months I would not be happy.

However, I would have thought if you had that kind of money replacing the motor is not a big deal if it bugs you that much. Horses for courses and not a problem I have to deal with :ROFLMAO:

Lets not exaggerate... we aren't mayflies and waiting for 6 months until something new comes out is hardly throwing away the best years of your life. :giggle:

Living in a hurry will only get you faster to the finish line.
Its good news for me if shimano makes a lighter motor that consumes less power and with even better software and less noise.
More torque is not so important as 70nm has been enough to crush more drivetrain parts in one year than on my whole biking life.

My main reason for upgrading my 2017 -> 2019 Levo was the Battery/Motor combo so if this is the case it will be welcome for many.

Thing is, what would you want from a drop in replacement for your e8000? More power? Maybe more efficient? Less weight? More reliable (Gary-proof!)?

Would you pay £1000 that, say?

The problem then is that the 504wh battery is not enough range for some or if going the other way it’s not going to match the Levo SL’s battery/motor combo weight saving.

In a new bike though there’s a possibility this could be addressed but maybe not. Time will tell but 2020 is looking interesting already.

More efficient and less weight would work for me.
Can’t comment on reliability as I’ve not had any issues with mine so far.

Thanks for the information! I did not know about this, but I'm surly overjoyed as 3 of my bikes have the du-8000 compatible chassis and this makes them future proof for some time.

I would gladly drop 1k on a bolt in upgrade that yielded 120nm of torque. I'd buy 3 tomorrow.

...assuming that battery size/format/connectors are the same as well...

Just as important as the EP8 motor is (I hope) a higher density battery in the same form factor, also a drop-in replacement. Hoping for 650-750 Wh.

Last year I made a video about the new Shimano motor. Just my thoughts about what to expect. I believe it will fit existing frames, and Santa Cruz might have made the right choice going with Shimano. Possibly.

Not going to happen, not by the time the new motor emerges anyway. There would need to be a major breakthrough in battery tech to get that kind of increase in energy density, and if that did happen all the production would be consumed by automotive and industrial uses first.

Its shimano, it will be good, shimano rarely do "first" but they usually do better. look at the bosch gen 3 compared to the e8000. or the 12 speed drive trains.
i wouldnt be surprised to see something full powered but sitting at around creo weight as shimano have the engineering expertise to do it rather than box up an existing hub drive like specialized have.

I predict EP8 to be similar size and shape to E8000, but made lighter (maybe magnesium or partly plastic or carbon construction) and maybe slightly more torque (75 Nm or so). As for batteries, I'd be very surprised to see similar sized ones with more than 600 Wh.

I also would love to see the option of a range extender/bottle cage battery option for Shimano systems. I can think of a few rides where I'd gladly trade carrying and extra 2-3 pounds on the bike for 25-30% more range.

I dont know if it was intentional, but with this move shimano may be creating the small block Chevy of the ebike world.

This instantly increases the value of any used bike with a du-8000 compatible frame.

I do hope that they can find a way to cram in more cells (going from I think 10p4s to 10p5s) while staying backwards compatible. That should give theoretically 630 Wh using 3500 mAh cells.
That’d be perfect. Good balance of performance/range to weight penalty.

Maybe the actual size of the shimano batterie is the best compromise between using one or two batteries on one ride (backpack) instead carrying one extender. For me, it is. Otherwise there would be a stronger aftermarket offer of extenders for the motor witch I guess is the best selling one.
The shape of the internal batt is no as backpack friendly, though.
