BOSCH CX Gen 5 Battery Range Test - Bosch Vs Brose, DJI Avinox, Shimano & Yamaha

[@SamsBikes]

So riders what do we think of the new range of the new Bosch CX Gen 5 motor?

[@adrianrogers6976]

Can't tell because you didn't include Bosch CX Gen 4 motor

[@grahameconnor]

Watched your other reviews on DJI avinox's motor. Super impressed with the power of the motor, 850 watts of peak power is definetly ground-breaking.

[@ricardorodrigues3508]

not really, you have bafang m560 doing 1500w and the m620 doing 2500w, but the more power you have the heavier the motor and less range as it drains battery, so at some point you need 1000wh battery to do like 30km, and a 30kg bike, the sweet spot is balance, i think yamaha pw x3 has nailed it, powerful motor with tiny form factor and weight

[@sergioLz123]

I've been following DJI for a while now, always been a fan of its drones. When I hear about them releasing a bike, I was super excited. And now with the Amflow bike on the market, I know for sure that DJI never disappoints. 1000 W of power for 30 seconds just blows my mind!

[@kenk8242]

The Yamaha PW3 is basically silent 85nm. Natural smooth delivery. Very little over run. Love it!!

[@markfawcett9654]

I never remove my battery, and love that companies like Orbea and Rocky Mtn have been able to opimize the design of the Emtbs, and keep them lighter weight, by NOT having the removable battery.

[@RichardsonJack]

It's always great to see different kinds of tests across different motors and brands. The range and battery tests kind of put me off tho. I did some research believe DJI Avinox has one of the highest torque power of 105Nm. Plus the test didn't take into account the weight and tire pressure of bike.

[@TCK71]

For me it’s go to be a removable battery. Thanks for the video. 👍

[@SamsBikes]

Thanks legend

[@jbonexc1725]

Great Video Sam. Love it when I get an Upload Alert! Next time can you add a "distance" graph too, so we can see which motor/battery went the furthest? RE: Batteries. Due to the climate in S.Wales, I think I would need to bring the bike in the house if there's a cold snap: 1) I don't have the space, 2) the Mrs would not be happy. With a removable battery, I could keep it in the house and leave the bike in the shed. The thing is, most the EMTBs I like have them integrated.

[@mitchelmckay3651]

100% removable, turbo levo with a extra 700watt in the backpack to swap out on a big back country ride in New Zealand. Old Ghoat road👌

[@Rideahr]

Thank you, Sam!

[@SamsBikes]

Not a problem mate

[@keith6872]

Increasing chainring size helps with range and reduced cadence. I went from a 32 to larger 38 tooth and love it. Bike still climbs hills like a beast using larger 12 speed cassette. Bike is a 2021 Rail 5. Removable battery to reduce weight for my bike rack.

[@SamsBikes]

Thanks super interesting

[@keith6872]

@SamsBikes Some ebikes will not accept much larger chainrings...larger sprocket will not clear swingarm. Luckily my Rail 5 will clear the larger 38 tooth chainring.

[@ferranox]

no way! maybe your uphills are not steep enough or not technical. for fire roads - yep, why not?

[@ollimustonen]

I have fatbike with Bafang M510 and 38 tooth front chainring and it’s amazing. With 12 speed SRAM I almost never use gears 1-2 still. And I have been climbing crazy hills with no problem.

[@ferranox]

@@ollimustonen than you should come to Finale Ligure EWS-E and show all those sponsored racers how to climb crazy hills! nobody uses 38T there! why?! :D :D

[@stevehartland7003]

Definitely removable for flexibility of charging when away from home, oh plus no cables through the head set, and separate stem and bars please

[@SamsBikes]

Thanks for chiming in on the battery 🔋 and yes no headset cables please

[@jamesandbrendaoates7637]

Great video Sam, makes me want to go out and buy a new Rocky Mountain Altitude.

[@marcoaguiar6608]

Hello Sam from the Azores/Portugal. For me removable battery. Specialized Turbo Levo beat's them all 😂😅😊

[@SamsBikes]

Thanks legend and yes I love my Levo

[@babajikathullu311]

Random recommendations,but honest video

[@Kev2Bee]

Internal battery, please. *for potentially higher frame strength combined with lower frame weight and arguably better looking designs. Aside from this the design and build complexity of the battery compartment, latches and cover are additional costs. *All batteries are removable, some being more difficult to remove than others. Yes, the convenience of external/cavity mounted vs internal batteries is obvious. What’s not discussed is frame flex, strength and weight of each mounting style. I don’t fly my bike ever, so I don’t need the convenience of externality mounted batteries. I own only one internal battery and ‘might’ buy a range extender (or two) for🎉 exceptionally long rides.

[@SamsBikes]

Thanks for letting me know all great points

[@32DH32]

You are one of few presenters who calls this new motor gen5 (luckily, don'tget why most of presenterscalls it Gen4 updated)... non-removable battery is no go for me. My bike garage is without heating. I don't want to store my battery at the freezing temperature. But I fully understand that this is lot less problem in Spain 😂 edit... I need sub 20kg bike for my roof top bike rack. Without battery is OK.

[@SamsBikes]

Thanks rider! Yes it’s very strange to me how this is not a gen 5 motor, it’s a new casing, new internals, small and lighter and different mounting points! So in my book it’s a gen 5! Thanks for chiming in on the battery, yes I totally get that so it’s a fair point.

[@Descent4love]

Removable Battery! 1. For maintenance cuz batteries go bad and 2. for me I dual purpose my bikes (not all). So I'll change tires and pump up the suspension and run gravel and road events. And when the event is 62+ miles (100K) or more, I have to carry an extra battery to swap. So, I look forward to the new 800 Bosch battery for increased range and that its smaller and weighs less! And Cube is great bike company! While other companies are closing factories and/or exiting the market, Cube has a FULL line up of 2025 Ebikes on their website NOW based on the Bosch Gen 5! And all with removable batteries! Cube has it together.

[@Nomads_Rowing]

Hi Sam, What is the official line from Bosch as apparently it’s not a Gen5 but another upgrade to the Gen4 internally with gear material and sound reduction at the crank plus exterior face lift and don’t class as a Gen5? Your deep dive tests have been a really good approach to emtb over other channels - i.e real world and back to back - top job ya Aussie emtb battler 😎

[@SamsBikes]

Thanks 🙏 legend! I’m not sure why Bosch are trying to down play a new motor. The new motor, has different externals and internals, different mounting points and a total different pedal stroke feel! So it’s 100% a gen 5 in my book.

[@Nomads_Rowing]

Exactly my thoughts especially after Shimano sorted out their firmware to improve the 801 as Specialized are hovering in the background with the next generation of their bikes and motor!

[@BlackFlag94]

For range tests, can you do a variant of yours whereby you simulate a group ride. I.e. you ride at the pace of the slowest in the group and therefore some bikes will be in lower power modes. This may mean that rider A on system 1 can do 800m VAM in their full boost mode.... but rider B on system 2 doesn't need to be in boost to do the same VAM and therefore increases their range

[@SamsBikes]

That’s a good idea

[@pauls1128]

With Bosch Gen 5 - removable so you could swap from 600 Wh to 800 Wh (e.g. Crestline) if your frame can handle the width of the 800 Wh. And as you mention, makes travel easier as you could potentially rent a battery.

[@JorenMathews]

Have you considered trying to match assist levels? The DJI presumably would gain range if you turned it down to match the other motors.

[@Stockfish1511]

Gen 4 on my rail has never run out. Im usually dead before it runs out. I have done like 4 hours in turbo mode and it got about 60 km and it was at around 10 percent battery left. 750W battery and im about 100 kilo myself. I think you are dead tired way before it runs out. Im big guy and very fit. But still cant manage to drain it. I think when you pedal hard and reach motors peak limited speed, the energy it uses becomes less because you are pedalling even though its at the speedlimit and the battery is then saved instead burning your own leg power. It might be the reason why i can get it to 60km without the bike being drained.

[@SamsBikes]

Thanks for your input mate i agree unless im doing a range test I don’t run out of battery haha 🤣

[@philbali3855]

Hello mate! Thanx for all your videos first of all!! 🫶🏼 You mention you travel back to Australia quite often… how do you manage to carry your battery in the plan? I am struggling to find a way to do that. Thanx hips Sam

[@SamsBikes]

Haha I have lots of friends! Normally I get loaned a battery in Australia 🇦🇺

[@philbali3855]

@@SamsBikes arrrgh! Good for you Sam. Shame the airplanes do not want to carry batteries. Such a deal breaker for me when it comes to travel with my emtb.😔

[@Pee01Key]

Hi. Great your work. Can U pls test kellys THEOS F70 ?

[@nomad-pq4yw8iy7v]

While the non removable removable battery can be a pain in the butt. It can have it's advantages and maybe worth it in some cases as well the fact that you can actually remove it just involves more time, skill and tools ( not something you want to have to on the regular).

[@emilysona]

I don’t mind if a battery is removable or integrated, but a removable one is definitely better for those who travel with their bikes, as large batteries aren’t allowed on flights. On the other hand, integrated batteries provide a stiffer frame, which is a nice advantage. So, both options have their benefits.

[@MANUELCOSTARODRIGUEZ]

I will like to see That test with a polini motor and oli edge becouse are great motors

[@emilysona]

Regarding the new Gen 5 motor, I’m sure it’s an excellent upgrade with many improvements. However, it’s disappointing that the distinct pickup and powerful push of the Gen 4 motor is gone in the Gen 5. This "kick" was what made the Gen 4 motor popular worldwide, especially for racing and general riding. It would be great if Bosch could add an option via firmware to bring back this characteristic, maybe as a setting called "CX-4" or "Gen 4 Mode." Shimano motors are being phased out of many bikes, so changing the motor's feel to resemble theirs may not be the best direction. Keeping that unique Gen 4 push would definitely be appreciated by riders around the world. I hope Bosch considers this feedback.

[@motoboggle7525]

Absolutely agree but in other reviews it has been reported to have a more powerful feel just smoother and don’t forget there an update on the way with increased torque that should help and also it’s still adjustable with in the app so you maybe able to increase the feel thro that 👍

[@pollyaloy]

​@@motoboggle7525I wonder what happened to the update ?

[@CpTnlAw]

I'm quite surprised of the autonomy. I rented a sunn charger last year with a 625wh battery and I managed to put 1800 D+ and 42km, probably had around 5% left. It was in the alps, crazy rocky trails, and i'm not super fit. (mostly tour and emtb, some boost near the end as my legs decided they did not want to push anymore)

[@rockandchilimtb]

When you mention the new bosch display, you mean the purion 400?

[@milanduda1454]

I'm really glad I have the Gen.4

[@SamsBikes]

They definitely are different.

[@nikolaschmidt5892]

I do have it as well, however, tell me, do you consider it noisy? I see everywhere that Bosch developed Gen4 to be quiet but my motor is really heavily noisy, sometimes so much that I see people I am passing turning around what sound is coming

How does it pedal with a dead battery as my specialized is like hard work.

[@SamsBikes]

The gen 5 decouples pretty well and it pedals pretty ok when the battery is dead

[@nikolaschmidt5892]

Do you consider it noisy? I have Gen4 (2022 build) and it is so noisy that people notice me coming in the city on street tires and I do not hear lovely quiet nature around me when I am climbing.

[@tomquimby8669]

So gen 4 or brose, thanks for the test. As for batteries removeable of course with the caveat of an magnetic battery connector. The standard prong and sprung pin receptor just are not reliable

[@SamsBikes]

Hi Sam can the 400 wh bosh power tube with 50 nm active line plus do 1000 meters in turbo mode? emtb weight 21 22 kg example trek marlin 8 +?

[@mikemac3726]

Was noticing the Bosch Gen5 test speed was 9.2mph average and DJI test was 8.7mph average. Bosch in Turbo mode and DJI in top assist without Boost?

[@SamsBikes]

How did you get the average speed? By just doing the maths? Remember I’m not a robot and I do stop for water and food ect. So would go off that

[@mikemac3726]

@@SamsBikesHaha yes distance/time you reported on the tests. Small difference so an extra 5 min food break would make all the difference. I think Strava or other apps only totals the in motion time though. The time is not just in motion time?

[@Lenswide]

Bikes with 22700 battery cells are probably better than 18650 cells at the same Wh due to better heat management.

Internal battery. Cause the downtube is slimmer, the frame is lighter because it requires less carbon layer in the downtube.
