Another Irish company. Some 23 year old whippersnapper from Cabinteely is the CEO. Seems in the style of a VanMoof but battery is removable. Too new for there to be much in the way of reviews.

That's impressive! Nice looking bikes too.
When I was 23 I didn't know my arse from my elbow!

Yeah same. Very impressive.
I'm actually tempted. It has a front motor though. Not sure what that would be like.0 -
Front motor is fine. Will give you all wheel drive (AWD)
But seriously, it makes quite a bit of sense to have the motor in the front of a low power electric bike. The motor assists. Go high power (thus not road legal anway) and it becomes a lot trickier. That's why you don't have any petrol motorbikes with FWDMy ads on adverts.ie:

Fair play to the Modmo lad, I too was once a 23 year old from Cabinteely, hope he does well.
Got this yesterday, have yet to give it a decent spin. Thought I'd be back in the office this year at some point so planning to get a bit more exercise.

Is that the Van Moof? Looks lovely0 -

That is a stunning looking bike, I think its beautiful.
If you painted it black and put on a basket it would be the big old heavy bike at the newsagents we used to do our paper round on, same bars and frame !!.0 -

Ohh, ok...... thought the chain was the issue there

It will do 200km no bother. As long as you provide 80-85% of the power and let the motor help you a tiny bit

The new WLTP for ebikes - make up any range figure you like.
I'd bet Bradley Wiggins or Chris Froome could go 500kms on an ebike with a 200Wh battery
.
It's clear in their FAQ page regarding the range............How far can SAIGON take me without charging?
Is the battery range really 200km?
Our '200km range battery' claim is based on real-life testing... and yes, it really is up to 200km.
Up to!!!
It's ridiculous marketing BS.0 -

Here is an interesting comparison. A Specialized shop bought bike costing the guts of €10k :eek: vs a home made bike from Andy Kirby, I doubt he spent more than €2k on it. The Specialized has to comply of course with EU rules about road legal bikes: 250W maximum, max 25km/h and only work while the rider is pedaling
It is so slow it is pretty much useless

Ah yes but remember the peak power of nearly 10 Kw
people forget the peaks and kill batteries fast when they're building ebikes and trip the BMS if they buy a battery and forget about the peaks, this is not good when crossing a busy junction! :eek:
But where's the fun in buying batteries ?
Indeed and doing it yourself is amazing fun once you know how to handle LiPo without a BMS you're grand and the ultra mega importance of Torque arms.
Custom built ebike frames are great but not for me who really likes to pedal, need to keep the weight down.
1 Kw into a direct drive hub is not that entertaining, 2 Kw into a geared Hub is to those not used to a bit of power, it's pretty decent I have to say, I was able to do 50 Km/hr on full throttle with 50v and the MAC 8T motor, 40 amp controller, was a great hill climber too.
I had to rewire my hubs too, best wire ever was the Alpha eco wire or something like that, it was really thin stuff but could handle mad current, opening the motors and rewiring was a pain. but well worth it.
Those were the days.0 -
Dunno about killing batteries. The mid drive Bafang in my bike is officially 750W but with a fully charged 52V nominal battery (at close to 59V), I get nearly 2kW. Even when using just 2 scooter battery packs (€25 each), this is fine, the batteries are still grand and if I have to replace them every few years that's just €50 and a charger is only a tenner. I bet you paid more for your charger than I paid for my batteries
These batteries are 7S3P each and I have them in series. I guess the capacity of a cell is about 2.2Ah, so at full wattage I put 30A into the pack which is (30A / 2.2Ah) / 3 parallel = C rating of nearly 5 not bad for a dirt cheap battery made of ubiquitous lithium ion 18650 cells...

I get nervous when my bafang (same as yours) pulls 1000w in case it damages the motor. lol if you havnt damaged it at 2k it would seem I have no need to worry!Dunno about killing batteries.

I have been toying with the idea of making a small light battery to throw into my pannier as an "emergency reserve" of sorts, but considering I get 100km plus range it would want to be some emergency0 -
Motor is indesctructible. Pretty much all electric motors are, direct drive hub, geared hub, mid drive. On a geared hub or a Bafang mid drive, at some point you will wear the nylon gears out, but they are cheap to replace. Did it myself in my fat bike with a front geared hub motor that was rated for 250W. I put a tiny bit more through it
That yoke was fun. Maybe I should sell my current eBike and buy a full sus fat bike and put the most powerful rear geared hub motor in it that I can find.My ads on adverts.ie:

I was running 20 C Lipo at the time which was a decent price and a 10 Ah pack so had around 200 amps at my disposal. Of course they had a lot better than 20C then and today but I didn't need it. But that could have giving me 12 Kw of power haha imagine, that's continuous power too.
Still, when I think that the little motor rated at 1 Kw could take 5.5 Kw and almost 10 peak, it's amazing the amount of power you can dump into a motor even if it's just for short bursts.0 -

Full suspension, a sprung saddle bar and fat tyres at low pressure all help there, SlowBlowin
