Begode Master 134V 2400WH Suspension

[Cerbera]

I wonder if that's the same noise I had today when I was sitting on it stationary, where it was proving quite tricky to find exactly the place to sit and where your legs should be, and when I wasn't at the rest  / neutral state, the motor made a low growling sort of noise of protest, which would also stop when position was adjusted slightly, and resume periodically until I stopped sitting on it.

Hey Everyone! Hope you are all doing well! I received my wheels 40T Master! here's my first impressions.

[Cerbera]

Day 3 for me of riding the Master in what started as light rain today, but the decision to go on a long training ride meant as I was still out in the open when it turned heavy and sheeting 20 mins later. Would my extra waterproofing, and the bits Gotway had remembered to do hold up to something a bit more serious in the precipitation department ?!

I continued to the country park where there was shelter, but an hour later there was no sign of it abating, so I closed my helmet visor, prepared to battle, and got her home as fast as I dared. I am pleased to say the wheel's behaviour was impeccable throughout, and despite a lot of training manoeuvres and experimentation with weight placement and trying to find the threshold for carving at various speeds without triggering the famous over-leaning tyre there were no falls, or even close calls really, so I count that as a win.

Got my first proper speed wobbles as I crested 45 kph on a downhill, but planted feet wide and solid, and gentle carving input stabilised me, and on we went...

Went up several big hills today. Pushed my luck, and the front pads a bit harder every time. There seems to be no limit to how much of that power you can just dispense - even if the hill in front of you is epic, you can just lean in, and there is the power - it goes up it, and it goes up it as fast as you'd like it to, and would go faster if you asked !

And the smoothness of the ride - there were several stages in that route that used to be absolute knee-shakers on my older wheel, that today were just as if they weren't there !I I don't think I felt a bump the whole ride, even when I wasn't on pristine cycle path !

I love that wheel more every day I spend on it. And to think I hesitated...

@massiestinymotors Pffftt - I laughed along with your hilarious sniggering at the compliance certificate - if you look closely, you may notice that the Master is not mentioned once in the whole document, though nearly every other model they make is ! Great vid btw  I get the click as well ! I added the triangle foam pad to the centre ridge, so it's not that ! It doesn't sound terrible or very severe - I'm ignoring it for now !

I am lurking for at least a few months now - and finally decided to share my experience with Master + comparison to ks-s18 and little v5f.
my stats: 
* weight: 85kg + gear (extra ~5kg)
* age: 38

My first wheel was inmotion v5f - good wheel for tricks and very light + friendly for beginners - although others say that it's easier to learn on bit heavier wheel  (I still keep it in a truck for a short rides).
After I started to hit v5f limit regularly and my back was hurting because of potholes and other bumps - I decided that I need more powerful euc with suspension - at that time I had to choose between ks-s18 and inmotion v11 - I picked kingsong - as I already had inmotion wheel and I wanted to try other brands (and also for the looks .. and kuji videos )

..so I got ks-s18 - in general - very good wheel (definitely recommend if you don't want to ride faster than 45km/h (although 50 is the max - I never felt comfortable to max out the wheel).. also it was lacking torque (not much, but time after time I was hitting limits - it tend to "skip gears" (dip a pedals forward for a 1 cm or so - and then quickly recover). So I decided that I need more powerful wheel with suspension.

I got my Master at ~10th September (from MyEwheel, Molicel variant)

* the main reason why I went for molicel is because li-ion batteries like to charge at 0.5c (in simple terms - approximately at the half of current of MAX discharge) - so potentially batteries offered quicker charging and also higher discharge at lower voltage + for me extra 300eur (comparing to LG 1900 variant) seemed as a good deal - I hate to save few $$ and then have a second thoughts afterwards.

* pedal height - it's easy to used to... no big complains there - to be honest - I am pleased that sometimes I can go over some stones without worry (although they could be adjustable. KS-s18 has adjustable pedals - never used that feature - too much effort (I believe 8 screws in total  ) - it's easier to adapt to pedal height

* comparing to ks-s18:
 -- suspension bound is softer (linear?) - small bumps are almost unnoticeable (except "clunk/click" sound on a very small, but continuous bumps - e.g. grass) - subjectively I like it better than ks-s18

 -- suspension rebound sucks - especially when jumping down (e.g. higher curve) - master tends to fully extend suspension with "clong" at the end. I tried to adjust PSI - but - put too low pressure and it bottoms out regularly, and too high pressure makes it extend even in a more bizarre fashion - never happened this on stock ks-s18 suspension. I settled down at ~300 psi - I believe one will need to fine tune psi for him/her-self - and little knob on suspension does nothing (at least I couldn't feel the difference - maybe I was testing on "wrong" bumps) 

 -- master has a LOT more torque - there are no hill which I cannot conquer  - sometimes it makes a scarry grinding noise (something related to incline and motor), but it gets the job done 
 
-- stock tire is more stable and less sensitive to road imperfections (in a good manner) - ks-s18 stock tend to "jump/react" too much - and sometimes I had a feeling like euc wants to throw me off the wheel (by reacting to small road imperfections - e.g. in a connection line between two asphalt layers)
I like stock CST tire at ~35 psi (I believe - one just need to get used to it) - I like it much better than stock ks-s18
- first few days I was riding with ~20 psi (stock/shipping pressure?) - it felt more stable, but energy consumption was higher (got similar range as with my ks-s18 regardless 2x battery size   - ~70km - at ~30km/h on the asphalt ). Please note that my range measurement is very vague - range heavily depends on speed and road surface and tire pressure and a lot of other factors).
Yesterday I was riding at slow pace (15km/h) while escorting another young rider - and after 30km battery indicator still shoved full charge

-- I never had "low temperature" display issue - although temperature outside has been below 10 degrees Celsius (I'm keeping EUC in a flat where average temperate is above 20 degrees)

* Bad things (but not critical):
 - I also have a little free play in pedals (reported before) - I tried to tighten screws in suspension rode's but without a luck.. to be honest it feels like a small gap in a motor (between magnets) instead of suspension play (I did not noticed it in a first few days). And it's sort of soft-ish change in pedal position (without an audible sound) and doesn't seem to be dependent on suspension psi (I have a hard mode in the app). 
The most noticeable way is to press tire at the wall - so it is locked in a place - and tilt the wheel forward and backwards a little (tire should be static and in the contact with the wall all the time).

- high pitch noise (~6kHz ?) - and it depends on motor (wheel) position - sometimes it's louder and sometimes it's inaudible (but when audible - it's not pleasant) - it's audible only when stationary - but still.. I would prefer to not hear it at all.

- lights are terrible (back-light is hard to see (and sometimes it is blue(!) and sometimes red (while breaking?) ) - and front light blinds others) - definitely needs a huge improvement (ks-s18 lights are much better - still not perfect either).

- it is on heavy side (40kg) - it takes some effort to put it in the truck.. I would not want to carry it with public transport - although v5f (10 kg) is prefect for trains

--------------
- I still haven't decided if I want to upgrade suspension - it seems OK-ayish.

What kind of range are you getting on that battery?

[EUCzero]

Regarding rebound adjustment.

The knob/adjustment  did no difference at 350psi. But at 150 it suddenly worked.

Yesterday I tested at 300psi, and it did not work.   Afggh. If I go lower psi than that the bottom out will annoy me constantly. But I wonder at what psi it will start working. 

kas-euc. Did you test lower psi in the suspension? Check. Maybe the rebound will start working if you lower just a little bit.

Anyone else noticed this?

Or should I just ask for a new suspension as mine does not work. Anyone else have effective rebound dampening at 300-350psi?

The rebound dampening clicker works for me at 300 psi. Opened only up to 4-5 clicks though. Past this it is not felt.

Edited October 17, 2022 by Aztek

[EUCzero]

For me, even fully closed behaves as fully open when at 300psi and above. It works normal at 150.

Today I will test 200, 230, 260, 290psi and so on to find the limit. Where the adjustment work and not.

[Magman116]

My New Master from Alien Rides is working great with @Freestyler FW.

I am in the 180-185LB range with gear and have the shocked pumped to 330PSI and the rebound control turned clockwise till it is nearly closed. This provides a slow rebound and cushions most of the bumps in the road.  Taking it to the trails, I turn the rebound control out 3  - 5 clicks to make it more responsive.

At first I set the shock at 380 PSI, but was so stiff. I let out a little air at a time until it was bottoming out which for me was at ~325 PSI. Then I added 5 PSI more.

I am just now recovering from a broken foot from a wreck on my RS HS so am taking it easy right now and not being too aggressive on the trails. I have it set up more for the street with the HK-666 tire.  It is near silent running and feels like you are gliding across the ground.  I have a Shinko 244 for off-road riding.

I did have to remove my Clark Pad complete system (fairing, bumper, and seat combo) until my foot gets a little stronger.  It is harder to ride with the added seat height and the width making it hit above my knees.  With the stock pads and the addition of one of my 3D printed brake pads, makes for a nice combination for the street and is easier to turn at higher speeds.

I also have a coil over oil shock to test out one day with multiple springs, from 1000lbs to 1500lbs.  I would also like to figure a way to lock and lower the suspension for more controlled street riding.

@wstuart
I cannot give you a very meaningful answer about a range - as I haven't made a range test + range depends on too many factors.
Trip to the office and back is approx. 15km - percentage reported by EUC world shows ~90% - my max speed is approximately 60km/h.
I had a very similar results (maybe 2% less on average) with ks-s18, only with slower max speed (up to 50km/h) and more gentle acceleration.
Also percentages reported by euc world tend to sit at 100% for a long time (first 5km app shows 100% battery).

Range never has been an issue for me - usually I'm riding for 2 hours on the forest roads and tracks and in those 2 hours I manage to spend approximately 30% (70% remaining)

Probably a better approach would be to record average consumption based on a speed and then interpolate potential range from there. I will try to figure out how to turn on logs on euc world and use them - or at least pay more attention to consumption.

@EUCZero
I haven't tried to adjust rebound(?) knob at a different pressure settings. But approx. at 250 psi my master starts to bottom out even on bumpy grass.

I also will play around with pressure settings tonight and report back results

Leashing yourself to the wheel in certain situations is completely harmless but will save the wheel.

The problem is that the rider is not in control on which kind of a situation they crash in. While a leash may have benefits in some situations, I also don't think that overall it's worth the risk.

 

20 hours ago, Aztek said:

Have you noticed a faint buzz when the wheel is stationary which disappears when moved forward/backwards about 1 centimeter and starts again when moved another centimeter?

As if at certain position of the magnets it buzzes and at certain it doesn't.

You are correct, it is buzzing when  the coils are between the magnets and the controller is switching between the two. Some wheels don't switch magnets as smoothly as others.

 

[EUCzero]

I am also trying to adjust the play in the slider system. No success. (suspension is now off) Even when I adjust the screws so much that the sliders don't slide, the back and forward play is the same. So.... I am very .... hmm.  not happy?

By situation I mean what type of scenario you are in, for example I prefer to use a leash if I'm doing a very steep long climb or doing technical off-road where wheel can fall down places, those are all slow speed scenarios and wheel will not have a lot of momentum to fly away, a tug on the leash will make it fall or stop.

Sorry to hear it, at least I'm not alone in this.. "Just adjust the screws!"

[Cerbera]

Do we have anywhere where there is a helpful table of compatible tyres for the Master ? Or has anybody in the UK got any recommendations for a primarily street (MC) tyre for my (V2) master that is in stock and available somewhere in this country !? Particularly interested in ones that don't need widening of the battery packs - I like the width of the Master as it is now.

Currently I I am minded to get this one - any thoughts ? Michelin City Extra 80/90 - 14 46P REINF TL

https://www.nationalbiketyres.co.uk/?route=product/product&product_id=68872

Is that gonna fit ?!  

This guy thinks it's too soft for racing, but racing isn't what I am going to be doing mostly - I want to be going at moderate speeds but with nice levels of comfort and control, and without feeling like it's going to fall over if I lean slightly too far !

 

Thanks guys.

They ARE in control of which situation they leash in though ! On wide open paths and cycle lanes I think we're safer without it, but in town and on cross-country trails we don't want that thing running away, where it can do damage to itself and omnipresent unobservant children (town), or fall off the edge of stuff (trails). I mean, I don't want it running away and killing itself in any situation, of course, but I do fear its vast weight, and tying that directly to me.

@Cerbera

I don't know what is available to you in the UK, but you could always order a HK-666 tire from eWheels or a Kenda K340A from Rev Rides.  Both are good street tires.  They work somewhat on the trails, but not as good as a decent knobby tire like the stock CST-186 or the Shinko 244 from Amazon.

[EMA]

@cerbera you can mount any mc tire 80/90-14 you can find, they are all really good, if you face lot of wet situation i recommend heidenau k66
 

[Cerbera]

Day 4 of the (re)learnings today and some interesting breakthroughs / realisations ! 

1. Don't fear the lean - when the CST does that thing where you think it's going to tip you - go with it and carry on  your move regardless, and so far... it doesn't tip ! It just feels slightly unstable for a micro second on harder turns. Have confidence, push forward, and it seems mostly alright. I still want the street tyre though !

2. I am having a lot more success getting up unsupported without worrying that the wheel will tip while it is held by one leg if I just reach down slightly with my right hand, and lightly touch the right side of the top, sort of hunching over and leaning forward as I step up, then straightening out afterwards. I imagine most of you won't have to do that, but most of you are a lot heavier than me !

3. Temperature was 18 degrees, so display powered up first time.

4. Did a bit more off-road after shopping today. The CST really is good for that, I feel really much more stable on rough and gravelly ground - something I did not expect !

5. Headlight is excellent !!! Stayed out way longer than I planned today, and it got dark on me when I still had 3 or 4 miles to get home. Turned on my light, and could see perfectly clearly ahead of me all the way home ! Unlike what I have read in previous review / comments, my light doesn't get brighter as I accelerate; it is constant brightness, and that brightness is very good ! Not feeling the need to swap that out any time soon. Perhaps it is one of the things they improved about later batches ?

6. Pads. I am trying to give the stock ones a go, because they are such excellent protection for the forward battery packs, and I'd like to make them work for me if I can.

At the moment I enjoy the variation in position I get between pushing on front and back pads, and I like the slide gap between them - I can see this isn't as instantly responsive as locked in third party pads might be, but I reckon it'll do for now while I am not trying to do anything too mad !

So. Today I tested rebound adjustment again. As I believed mine actually was working on lower PSI. Well it do not. Only for a few up and downs, then no dampening.
150, 200, 250 and 300 tested. Only difference vas that on 150 it seemed to be dampening, but then... no.
Also. My knob is very hard to twist. How is yours?
 

The foam hack preventing hard bottom out at least help. But now I fantasize on putting a second damper where your guys told me to put the foam. I will probably not find anything that will fit under there, but at least I have the fantasy.  

[Robse]

sometimes it makes me wonder, what will be the name for the next Begode wheel  "Servant"?  I better go to bed now

don't wast your time with stock shock, it's garbage, get a simple coil and you'll be surprised

This makes a lot of sense.

Due to the improper design of the shock actuating linkage, the shock is insufficiently compressed. Thus, it make a lot of sense to use a coil spring instead, since the spring rate is linear.

I suspecting that there just isn't enough stroke available to properly to utilize an air shock effectively.

I know its initially impossible tell, but I recommend finding some way to make sure that the clunk you are hearing is not the the lower part of the wheel twatting that single screw that protrudes down from the MB box around half way into the depth of the wheel, which may directly contact the BMS board as I recall.

I read in other threads, or perhaps further up this one, that Begode had started including foam pads here to alleviate that problem, but mine doesn't have any that I can see... ah yes there it is from @Raptor's post on page 73...

That problem aside, I am delighted to hear that you didn't cancel in the end, and are enjoying your new machine  Happy riding dude !

Oh, good info, I’ll check tomorrow. Just fyi, I hit 45 mph today but only seated since it’s been windy and not conducive to high speeds while standing. My PWM just touched 75, I have it set to 80 so I think I can hit 50 mph for a short while and that’s w full battery. I’ve ridden 40 mph for long stretches, several miles but it eats my battery too fast. Anyway, so glad I went ahead w the purchase and loving it more each day. Thanks @Cerbera, been following your threads but been very busy w other life “things” recently to chime in much.

One issue I wonder if you or anyone else can tell me if I should be concerned about. My Master only charges to 133.0v even after leaving on the charger several hours after green light comes on to balance cells. According to Darkness Bot my battery reads 100% but 133.0v vice 134. Begode app doesn’t show voltage which is very Begode like. I don’t have the tools to check individual packs so I’m contacting  EWheels about this tomorrow. The wheel rides fine otherwise and also surprised how cool it runs.
