Do eBikes belong on the mountain?

Written by Lance Branquinho.

It’s been a year. Since their arrival. These most unprincipled battery bikes, with on-board power aiding their propulsion.

Much like creeping taxation, quinoa everything in restaurants and mobile data pricing, the ebike draws our collective ire. Judgement is absolute and crushing. ‘It’s not a bike. It’s a motorbike… If you can’t ride, go spin on a Wattbike at Virgin Active. Get fitter… They’ll ruin trail access for all of us’.

A year on, from the first proper e-mountain bikes (e-MTBs) becoming available in South Africa, has sufficient time passed for reflection, and perhaps, appraisal? Well, before Pravin’s next budget, where ebikes could quite possibly become another tax revenue item, instead of an incentive – as they are in Europe, my feelings toward them have altered.

I should be the prototypical ebike hater. My mountain bike is a South African brand single-speed 26. Crisis. Could I be more fundamental in my traditionalism? Yet I’m conflicted about these battery mountain bikes.

They’re not motorbikes

Obvious for some. Less so for others. If you use the most sophisticated e-MTB available in South Africa, which is Specialized’s Levo, it’s categorically obvious that they’re not motorbikes. Mopeds would be a more plausible correlation, but without a throttle, and cranks which turn, the motorbike/motorped association is plainly false. And facetious.

These are mountain bikes with pedal assist battery motors. They’re not off-road motorbikes with single-crown forks. Components are sourced from the bicycle industry, instead of motorcycle supply chain.

The hate, though, is real. Online polls register disapproval numbers in excess of 80%, damning the e-MTB’s existence. But we all know the internet, with its self-appointed crusaders, is rarely within a margin of reflecting reality. In Europe, where cycling sources its history and hosts its most credible events (road/XCO/DH), e-MTB sales are near surpassing those of non-assisted – dare I say ‘conventional’ – mountain bikes. I’d always table sales statistics as the truest representation of acceptance and trend. With e-MTBs, there’s no invalidating the numbers: in parts of Europe, e-MTB sales are 50% up year-on-year.

Are they moral?

The primary salvo of criticism against e-MTBs has been ethical: if you work less, how dare you have access to my realm of adventure. Earn your turns.

In racing, certainly, there’s no argument that as e-MTBs become more sophisticated, there’s a risk of BB-battery motor solutions becoming sufficiently compact, to be near undetectable. Especially at races where organisers don’t have the sophisticated X-ray equipment.

E-MTBs don’t belong anywhere near a mountain bike race. Not even in a separate category. And if you analyse Specialized’s Levo, that’s hardly its purpose. This is a trail-bike: dropper seatpost, Pike fork. It’s not meant for stage racing. At all. It’s meant to enable those who have perhaps past their peak or are burdened by schedule or health issues, to recapture the thrill of trail exploration and riding.

It’s why I struggle with the enclave argument of having to earn your turns. There are riders in their 60s who are in great shape, examples of life-long discipline and training commitment. Age is a real keeper of ability, though, and why shouldn’t they have the privilege of participation on those fantastic five-hour Sunday trail rides? They’re the founders, with great stories, still chasing the thrill. Why deny them? Perhaps more meaningfully: why deny the unqualified excitement of a 60-year old refamiliarizing themselves with off-road cycling after four decades away from bikes?

Kids. Partners. It’s a similar logic. If your partner or offspring wish to join on a weekend ride, yet are petrified of the discrepancy in endurance between yourselves, why isn’t the e-MTB a great solution? It enables a thoroughly testing training ride for you, without risking the frustration of waiting at the top of each gradient for ten minutes.

They’re interested in this world unfamiliar to them, yet so beguiling to you, with its tremendous gatekeeping function of fitness. Is allowing family or a non-biking friend this glimpse of access, to aid understanding of your training commitment, really an unethical sacrifice before the mountain bike Gods? I struggle to think it could be the case.

Do they destroy trails?

Beyond the issues of ethical pedal assistance, trail destruction is the e-MTB-hater’s most vocal objection. The belief being that e-MTBs will enable riders so many runs, on a heavy bike, they’ll accelerate trail wear beyond all reasonable expectations.

It’s an absolutely rubbish claim, revealing an issue around trail wear and maintenance that’s conveniently ignored in South Africa: mass and bike set-up. Heavier riders, will harm a trail more. Heavier riders on relatively narrow, stage-race width tyres (at high pressures), will do this even more so.

Granted, The Levo is far heavier (22-and-a-bit-kg) than an aggregate South African rider’s bike, but the diversity in rider physiology rebalances this. How many rides have you been on where there are both 70- and 90kg riders? Exactly. The combined mass is what matters and most Levos, with rider, would equal the weight on many larger, fit, South African riders on their carbon marathon bikes. On a Levo, that mass contacts the trail through a much wider 27.5 plus tyre, which means less damage and potential brake lock-up.

Seeing the wood for the trees: e-benefits

As a purist, the concept of pedal assistance grates me. But I don’t live in an isolated Karoo valley all on my own. The momentum of trail access is empowered by participant numbers and people of influence – and they’re mostly mature stakeholders, unlikely to threaten Nino in a VO2 max test. If there are bikes that make these influential stakeholders ride more frequently and further, they’ll chair the negotiations for greater, lasting, trail access.

The burden of time, distance, and family are real. If your sanity and balance of zen depends on that specific singletrack descent, which is just too far from home within the time constraints of your scheduling, an e-MTB is not a tool for the lazy. It’s salvation for the committed.

Of all the unconsidered benefits of e-MTBs, safety is the outlier. Imagine a member of your riding group has an off in technical terrain, and you’re at the bottom of a valley, with the nearest mobile phone signal at the drop-in point you’ve just descended from. You have a problem. The ability of an e-MTB to get back up faster than anything else, and make that emergency call for help, might gain those crucial few minutes between a manageable evacuation and the delirium of an emergency evacuation.

Family. Kids. Dogs. Businesses which operate on weekends. I have none of these things in my life, but some of my friends do, and I’d like for them to have fewer excuses not to ride. It’s the reason I can’t bring myself to hate ebikes. Except when a 60-year old on a Levo is chatting away, whilst I’m close to exhaustion near the crest of a climb. Guess I need to train harder. eBikes make me a better rider. And I don’t even have one.

I recently came to own an eBike. It isn't a scrambler, very few of them are (the Greyp bikes are an exception and aren't really bicycles). My bike nominally outputs 250w, which is less than what I can manage. So, in terms of feel, it's just a normal bike with a bit of a boost. If you want to climb something steep and/or technical you still have to put in effort, the bike won't do it on its own. My bike is heavy and so requires a lot more wrangling than my normal bike. Hope that helps.

in other news i did a bikepacking trip with a "gravel ebike" in our group the other day - perfect tool for the job.

can we just moan about those here, or will we need a new thread for that?

 

 

 

Got nothing against wimps and disabled people riding eBikes anywhere. :-)

100%! Touring on a motorbike is a great way to see the country!

 

 

 

 

 

Yes that was a joke designed to take us aaaaaall the way back to "is an ebike really just a motorbike with an alternate fact name"?

I don't think it is a transition. It's another just another parallel option like gravel bikes.

Chris, how is the E-Bike going up to the Mast at Conters ... does it hold it's line or do you find that the nose wants to lift under power? If so I imagine with the extra power it must take a good bit of body language to keep the front down.

 

With a "normal bike" one has to already shift to the tip of the saddle at the worst inclines to keep the front down and tracking true.

 

Bear with me, as I answer via but of a turn ....

 

 

Just after lockdown I cycled from home, had coffee at Bloemendal, then returned home via Traverse.  At least that was the idea.  Just above Blue gumm forest I looked down and realised I had messed up properly !!  I had 12 minutes to get off Traverse .....  For a moment I considered turning around, then thought what the heck ... BOOST !!  The Giant has 5 power levels.  I went to 3 and was at the speed-assist level in two peddle strokes (the Giant is set to the American 32km/h assist limit) .... kept it there, and when I got to the first hill I took it to max boost.  On a couple of points I would slow down for a turn, then power out of the turn ... spinning up the rear wheel !  :eek:   It is scary just how much power is on tap when you use max boost !!  I actually turned it down to level 4 to keep the rear wheel from spinning.

 

And yes, I got to Odendaal gate with a minute to spare.

 

Climbing from Conties to the Mast I leave it on the third power setting, stay seated, spinning at about 80rpm, leaning slightly forward, and it iddles up the worst bits in total control.

 

 

The more tricky skill to manage is steep climbs AND sharp switchbacks .... when you back off the rpm the power-assist falls away, then when you get back on the peddles you can get a bit of surge pushing the front wheel wide of the turn ...  just another "skill" to master with these bikes.

I took my bike up there today and yes the nose does lift a little occasionally ahahahahahhaa, but nothing troublesome.

 

I usually get off on the concrete slab on my normal bike  :D

I cycled up to the mast the other day on my current normal bike, and I have to shift onto the nose of the saddle to keep the front wheel true. My previous normal bike was longer in the reach department and took less body language. 

 

The concept of assisted power on the climb had me wondering if it accentuated the front wheel lifting or not tracking accurately.

Hairy I was thinking of this post on Sunday morning, while riding up to the mast from Conties side..... seeing a rider in the distance walking the last bit .....

 

 

As I approached that short cement section I was lowering my shoulders .... along some sections my elbows were almost 90-degrees.  But all the time I stayed seating to keep traction on the rear wheel.

 

After the cement section there were 2 or 3 moments when the rear wheel wanted to spin .... so I had to find that sweet spot between balancing the weight between the front and the rear ....  through all of this I did manage to keep the front planted.

 

 

 

It also gave met time consider the benefits of different "power assist levels" ... and its impact on the ridebility of the bike .... to only refer to the "boost level" certainly is a small part of the story, and often misleading.

 

 

For the GIANT the the following numbers apply, though the same reasoning applies to all ebikes.

The Giant has 5 boost levels:

"1" Eco = 100% boost.  Thus for every 50W you put in, the motor will add another 50W

"2" Eco+ = 175% boost.  So now the motor adds 87,5W for every 50W you put in.

"3" Normal = 250% boost.  Now you get 125W for every 50W you put in ...  :thumbup:

"4" Sport = 300% boost.  150W added for your 50W ....

"5" Sport+ = 360% boost, ie 180W assist for your 50W.

 

 

Please note the following :

- I deliberately used a low 50W input power example, as this is easy to put down when coming through a sharp turn or pulling way .... and suddenly you get a "burst" of "50+180=230W" on the back wheel.  This is when you get wheel spin out off slow corners, or the nose pushing wide in hair pins - while using maximum power assist.  Using levels 1, 2 or 3 (depending on the gradient) really helps to smooth out the power delivery to the back wheel !!!!

 

- the maximum assist power from the motor is 250W .... so when I am riding using assist level 3, I need to put in 100W to get the maximum power assist from the motor.  Even if I stand on the pedals and put in 400W the motor assist will only be 250W, irrespective of the assist level - and only while my speed is less than 25 or 32km/h.

 

- as such, using the higher assist levels negatively impacts the handling of the bike at low speeds.

 

- the only benefit of the higher assist levels is when you are doing longer climbs and are too tired to put in 70W (for max assist on level 3) ....  at this point you really need to start asking yourself if you can still concentrate on the trail if you are that tired .....

 

 

 

- uhm ja .... the higher assist levels are handy during the morning commute, to get you to the office without building up a sweat ...  :whistling:   :ph34r:

I test rode a Giant Ebike on holiday a few years back, could not stop smiling because it was a riot.

 

That being said if you have a reason for an ebike like an operated or weak limb, maybe you are older and very unfit, any illness like diabetes or such then by all means go for it. If you use an ebike just because you can well that's your decision but you might be missing the point of cycling and pushing your own limits. 

 

If all you care about is someone crushing your KOM then you have forgotten what it's all about.
