Stihl riding

[PDoz]

If only this was a thing....

So I'm looking at the stihl electric chainsaw I bought myself for xmas and realised the 280 wh battery only weighs 1.8 kg and is $1 oz oer wh ( ie half the cost of out emtb batteries per wh) . They even do an ap100 with 79 wh , so legal for flying with? The saw itself is only 2.9 kg ( plus battery) so viable to carry on the bike for track maintenance. It's got me thinking....

The stihl riding range ?

Imagine an emtb that accepts the ap range batteries , Carry as many as you need for the ride, easy to swap out as they discharge. Build me a kevlar ruding bag to fit the front triangle, it holds a few spare batteries and a saw, plus it folds out to be a sawing apron / chaps...perfect for track maintenance, our friends at forestry can experience the joys of emtb and hopefully realise we're not evil....plus some lucky bztrd gets a job riding the thing around mtb tracks / fire trails looking for fallen timber to clear!

Hmmmm....a version for the armed forces?

I don't think @PDoz the Stihl battery can deliver high amperage for many hours.

I use an electric chainsaw for trail maintainence that I carry in a back pack I just happened to have that fits it just right.

They are great trail tools, quiet(er) and no stinky gas to deal with and get the job done in much shorter order than bow saws and the such. The pack weight isn't too bad but I wouldn't want to add that weight directly to a bicycle.

I don't have any input on your battery idea but have thought that if you could plug the saw into a 48v ebike battery, my saw is 48v as well as my bike, then you could do away with the battery weight as I carry two to make sure the job gets done the first time....

But as it turns out I do need to go back and get pretty much the whole tree out of the way because it's covering the new/old trail exit I discovered today testing out my friends new E+ Pro where I found another piece of logging gear, the winch section of a Donkey engine that looks like it's been there awhile.

Lol.. I've thought the same wandering the power tool aisles! Ozito actually released an ebike a number of months back that quietly appeared and then just as quietly disappeared at Bunnings. It runs on the same batteries as the power tools. https://ozito.com.au/main/wp-content/uploads/2019/06/PXC-BIKE-KIT-Online-Manual-COMBINED-Ed1.pdf

Aldi did a similar thing, but it was hub drive and, well, a bit aldi.

The reason I'm fantasising about the stihl range is they have a semi pro level battery system - the ap battery can deliver enough performance for a 450 mm chainsaw , or a decent pole saw / brushcutter. MUCH higher output that our feeble 250w mid drives!

Oh...and they have a battery backpack....1500 wh 36v backpacks.....in ktm orange...https://www.stihl.com.au/STIHL-Products/Battery-Power-By-STIHL/Battery-Range-Overview/Batteries-Accessories/295347-1613/AR-3000-L-Backpack-Battery.aspx

Very interesting design... I wonder if anyone on EBR owns one?

I don't have the specs in front of me but the AP300 would not run a ebike very far. But I have a AP300 battery laying around here somewhere (I also have the 160 battery saw) and it has come up for discussion. I know a company called BMZ (I'll verify the info at work on Weds.) is making a universal range extender the size of a jumbo water bottle, and it obviously fits in a bottle cage. I may try to acquire one for "testing" purposes but I didn't see Rad listed as a compatible ebike.

The ap300s has more grunt that the ap300 ( 259 wh vs 227 wh) . , it's around 1.8 kg which makes it half the weight and power of my giants battery. ( my 500 wh battery weighs 3.6 kg) , But the stihl is 1/4 the price....

Imagine having the choice to clip in 1,2,3 or even 4 batteries depending on expected ride duration, or even being able to clip in an ap 200 for an hours riding (1.3 kg for 150 wh). So, theoretically, my bike could be 2.3 kg lighter when I nip out on my training route ( I only use 90 wh on my 1 hour rides ). Or I can ride a full day with 1000 wh of batteries , say 4 x ap300 s in a backpack.

More importantly, imagine having a universally available battery system that was cross compatible with garden tools. You could borrow your mates chainsaw battery as a range extender.

Is BMZ located in Poland? If it is they are great to deal with. I used to get a lot of electronics stuff from them.

It is a German international company with facilities in Germany, China, Poland and the US. AFAIK, Bulls Bikes use BMZ batteries.

Sounds like I may have dealt with the Polish corner. Hopefully if you do end up dealing with them you have a similar experience to mine and all goes well for you.

I use this adapter & DeWalt cordless tool battery as a "range extender":



The battery is 1/3 the size, capacity & price of an OEM replacement battery so there is no economic savings. I use it on rides that are very close to the range provided by my OEM battery as a backup. That way, I don't have to carry a second much heavier OEM battery as a spare.

These adapters are available for many battery brands and are a simple matter to wire up to a bike. You need to be sure the battery you're using is capable of high current drain. Many cheaper tool batteries aren't. More specific information is available in this thread:

The US branch of BMZ is located about 4 miles from my house. I've yet to go there but some employees from the company I work for now work at BMZ. BMZ is currently servicing our (company I work for) battery research products. Someone (not me) from my department gets to go there twice a week. I wanna go there so bad! So I'm slowly starting to learn a bit about battery technology, since my current skill set relies on 2-cycle gasoline products. I don't see 2-cycle gas products going away completely by my retirement but I would like to at least have a heads-up on battery tech.

Great idea, just strap it on when your going long? I bet you’re glad of it when your bike controller starts blinking? Neat find

There are a number of power tool battery-powered ebikes on youtube. But this one was one of the first, and definitely the most thought out and coolest:

Amazing craftsmanship on that custom bike!
