Tern Orox S12 Review | Pack it In, Pack it Out, Pack it ALL

[@StacyODell]

With a more tarmac-ready set of tires I can see that thing being packed to the gills for a really long distance trip. It looks like an absolute unit. If it has a 4A+ charger, even better.

can we get some commentary as to why these mid drive motors are performing slower on a hill relative to the hub drive counterparts like the Globe Haul and Aventon Abounds? Also can we start testing these things fully loaded as they will be used in the field? I'm wondering if mid drives perform better with cargo than the hub drives.

[@letsgoOs1002]

Hub drives are built for speed but not for low end torque or efficiency. Also as you get stronger legs and are on longer hills mid drive will start speeding up. So stopping and starting on a hill is much easier on a mid drive compared to a hub. Also mid drives weight is less and since the drive is more in the middle of the bike it's easier to put tons of cargo without being too heavy and becoming unstable. With the rhloff hub and mid drive you can conquer massive hills where the hub and certain grade will get maxed out pretty quickly. It's a trade off. Do you want speed at the cost of efficiency and weight or do you want less weight more efficiently but you have to put more power into the bike.

Being able to scale a slope depends on the amount of torque each motor puts out, for mid-mount motors, what is the impact of gearing and losses through the drive train. Most bikes don’t have rear gears larger than the chainring, but the Orox does, so it can multiply the torque of its motor sent to the rear axle, at the loss of distance per crank rotation. But most mid-motor bikes don’t, so they deliver less torque to the rear axle than the motor puts out. This is often why a mid-motor with the same torque output as a hub motor doesn’t seem to climb hills as easily. It doesn’t help many mid-motors output less torque than a hub motor, and unless they use a stronger chain, they have a practical torque limit or risk snapping chains often. The speed you sustain with just the motor, assuming it can overcome the force required to climb the slope, depends on how much power you send through it. Power = force * speed.

Some great answers here. A simple answer is that hub drives definitely club hills easier when fully loaded. when I first started riding e bikes I could not get uphill with a full load. When I got a Bosch mid drive motor I have been able to climb some of the biggest hills with a full load.

I own an R14, and the most challenging aspect is traveling. It is a long, heavy bike and there are not a lot of bike racks to carry it.

[@ElectricBikeReport]

That makes a lot of sense. We're testing a rack now that may be a decent fit, stay tuned for that review.

[@thegiantswordworkout]

Nice Reviews! The whole point for the Tern Orox is being able to load it up to max payload but no one has tested it in this configuration which everyone wants it for. We have no idea the mileage and performance loaded to the weight brim. PLEASE DO A LOADED REVIEW! 😊

[@maksymvinyarskyy2813]

Tern Orox 😍🥰

[@donrossi277]

What is the wheelbase? Looking at it standing on end, it appears you are going to need at least six and a half foot of bike rack.

[@lucmoncourt9337]

i will love it with a 5000W motor

[@FWS_Sinister]

i read the title as Pack it up Pack it in like Jump Around by House of Pain, would've been a cooler title lol

[@ElectricBikeReport]

You're not the only one, there was a lot of talk about that here at the office :)

[@ElectricBikeReport]

We had the same thought and played that song in the office in tribute :)

[@Alby_Torino]

For sure not with those tires. But I'm sure it's so rigid that with better tarmac tires it would be uncomfortable

[@cerebrix]

That things 7 grand out the door after tax and shipping though.

[@reggydavis]

that's miata money

[@jfly2249]

No suspension? $6500? No way! That bike will perform poorly off road compared to even the most rudimentary full suspension bike. Not sure who would buy one of these, maybe an Uber eats guy in Beverly Hills?

[@thegiantswordworkout]

It would be amazing to get weight adjustable suspension on this bike that you can adjust when you load it to its 460 pound capacity. I wish they had done a longer tail like the Surely Big Fat Dummy for transport of lengthier options. Other than that homefully it's amazing for offroading with gear loaded heavy. I search once a week for a true loaded to the gills weight review on different terain and range and no one is showing a review that's applicable to the use people would chose this bike for its steep price.

[@BikeShopGirl]

unfortunately suspension doesn't exist for that weight capacity. Also suspension = maintenance :)

[@ammagato]

Sembra buona, peccato sia rigida.
