K2C & e-bikes

[Eldron]

I stubbed my toe last week so I think they should stop discriminating against mountain bikes and e-bikes at Iron Man.  It is just not right that an event can stipulate the type of bicycle that can be used. 

While I am at at, I think we need to re-look at the wet suits allowed and I am sure roller blades are the same as running shoes. 

 

Is it Friday yet !

 

Tryathlon!

Tryathlon!

This looks strangely familiar

Now that actually looks awesome beside the segway...

Given that e-athletes have real medical issues preventing them from running, riding, breathing or standing up - it's only fair they get to use mobility scooters

I am rubber you are glue - everything bounces off me and sticks to you.

 

Roses are red, violets are blue, ebikes are not bicycles and don't belong in races. Boohoo.

 

Damn. I really thought that would make me feel better.

cute, I got a poem!

 

 

in other news this thread has overtaken the "ebikes in races" thread,

https://community.bikehub.co.za/topic/163005-electric-mountain-bikes-on-a-mtb-race/page-1

 

but is still miles behind the "ebikes on the mountain" thread.

You'd need a dropper post for K2C, what with all the bad backs and terribly rough roads.

I hear you. To me race is a competition and there's prizes of monetary value up for grabs. Fun rides could be timed or not but there there's only ego, bragging rights and Strava KOM's /segment leader rights up for grabs. That's how I distinguish between the two. Not right or wrong, just the way I see it.

I have no desire to race an e-bike.

I also don't think anyone asking for e-bikes is wanting to race them. OP wants to enjoy and experience the vibe of riding along with others since his physical condition doesn't allow that from a normal push bike.

 

I also feel that the abilities of Class 1 E-bikes are being way over stated. Range is calculated for a flat smooth road and an average weight rider aboard the bike. Just looking at the nominal output and  W.hrs of the bikes available they all appear to be around 250W nominal and 600W.hr which isn't going to get a 80kg rider to the finishline at 250W. The bike would have to be more conservative in its output. and assuming the riders contribution remains failry low at say 70W Normalised Power, and the bike in conservation mode (to get the range) at roughly 120W

you're looking at 190W for the ride which is at best mid field

Yes

 

But this opens the door for top cyclists to be motopaced by other top cyclists for the win.

 

Adding 120 wattys on to Karl Platt even in his old age will allow him to tow one of his team mates to the win.

 

I dunno. I really don't care. If you guys want e-bikes at races then cool. I don't really do races anymore because I would prefer to ride empty trails when everyone else is racing.

 

Guys are being called names, people are being mean and petty and personal now. Over e-bikes.

 

pffft......

Haha - according to this, if a 100kg of you (with bike et al) cycle at 60rpm / 18kmph, on the 'tour' setting, you might just have something left in the tank going up Simola!

It seems to support my thinking:

 

100kg all up weight (conservative and on the higher performance end)

Power Pack 500

Active line motor

eMTB selected

 

for an average speed of 17km/hr you'd get 108km of range at best in ECO mode.

 

to get any sort of race winning performance out of the eMTB you'd need to have around 1300W.hr pack since its going to be more than x2 as heavy as a the Power 500.

 

Most e-bikers are going to be pottering around the mid to back of the field anyway just by virtue of the battery limitation. Ain't no body "racing" there

did you set the terrain to mountainous?

The range comes down quite a bit.

Most e-bikers will be pushing a lead sled long before then.

They have to go slower just to last the distance

Everything is relative and it depends who is on top of the bike.

 

Spesh LEVOs run 504kwh batteries. Basically 100w per hour for 5 hours - that is an enormous amount of power when considering competitive guys will run 250-300w.  30% faster for the entirety of the race is a lot of extra horses.

 

Pop that battery on a road bike and you could have an extra 200w for the whole race - insane! Sub 3 hour 100km road races would go from a decent challenge to a doddle. Even for an intermediate rider.

That's 100% true, but that's with current tech. In a couple years we will see smaller, higher output batteries and higher powered motors. Just a matter of time till the average Joe can do a 100km race at 30km/hr.

I reckon anyone who can a 4 hour 100km will happily roll a sub 3 on today's tech.

For sure, based on the time I've spent on e-bikes I'm confident that I can do a sub 3 100km ride (elevation dependent and on the road), and that's on a Spaz Levo with 3.0" tyres. Big statement - I won't bet my house on it, but I'm reasonably confident.
