Hello

I am in the process of planning up my first e-Bike build using a LHT frame set, with 26” wheels, and am wondering if the bionx frame mounted battery would fit on the third attachment point?

As a heavier rider at 290, give or take a pint of ice cream or two, I am concerned about the power of the bionx system with the 350 motor sizes, and their battery power with about 500 pounds of man, canine, and steel moving around Portland, with the desire to climb some of the better summits for photography with my canine.
Bionx is the only brand that my LBS can order, so it adds small comfort since it would be there head ache if a mishap occurs. As they always say, you get what you pay for, and security is expensive.
On the other hand

It looks like there are more powerful units (48v 1000w) motors and Batteries on Ebay, but I also understand the risk associated with this route if something were to not work out.
I do want a system that has the capacity to have peddled assist for when I am commuting, but can throttle like a scooter on down days with my health, and be in the middle when I have Wally. Comfort and reliability are more important than just out right speed.
Just looking for other perspectives, and to see how much I am over thinking this.

Check out the systems at Electricrider. They aren't pedal assist like the Bionx, but they do offer cruise control and throttle, which superior and simpler (IMHO). You get a lot more bang for the buck there.

If you or anyone that wants to use the BionX system as a Mo-Ped type of bike then it would probably be a mistake (in a hilly area for sure) as it was not designed for that type of use... On flatter roads you can certainly use it that way but the range would be tremendously reduced. On my 350 I can easily go 60+ mile distance on level 1 and 30+ mile distance on level 4 assist and I was pleasantly surprised. Then I lent out my bike to a buddy, explained how it should be used, told him of my mileage expectations and when he came back with only 10.5 miles on it and the battery dead, I was shocked, so using the throttle for the whole ride and not pedaling is not the BionX's strong suit... EDIT; People getting into E Bikes need to realise that there is a difference with how one can/should use an E-Assist Bike as compared to how one can use an E-Bike...

Having ridden both a 1000w (legal here in OR btw) system and the newest BionX 350w I would say for sure go with the 1000w with a minimum 36v, 48v preferred, 12ah Lithium type batterty for your needs. Wake @ the ebike store on Alberta is probably a good resource for you?

Well thanks for the reply's.
To catch up, I have my shop ordering the LHT disc frame set, which will be in on Wed, so the bike is in process.

Also just had lunch with my buddy, and he explained the same thing regarding the Bionx, and what I should have. Main point is that if a kit is tested with only half of me, it can only bring the other half halfway.

I am looking at the e-bike kit here:
https://www.e-bikekit.com/shop/produc...ive-136-4.html

and continue to just search for the battery.
By buddy built up fear about the stability of a lipo battery, but I also don't want to haul 20 pound battery.
But with this process, while slow, I hope will yield the perfect balance for me.
Question:
If I have a kit that does not do the PAS, can I still just ride the bike as a bike? The site reports that the directive drive has some drag, which is no big deal, as log as I can still just take a gentle peddle down the spring water listening to the birds in the morning. Than have an epad to drive Wally to the park in his trailer after work. I also still need to peddle Wally around for his evening walks, which are about 5 mph, and 4-7 miles long. Wally likes to sprint from park to park to play catch.

Thanks

PAS is not needed to ride any ebike "as a bike". It rarely takes any more than a few watts to counteract any drag of the motor.

OK thanks

just trying to get the details figured out.

Since I will not be transferring the current stem that I currently am using, in the part swap, so am thinking of the FSA Havoc stem. At 65 mm it is short which is required for my fit. Looks nice, and is reviewed as strong. Almost done with the build list thankfully, because I usually don't have the the time to research everything.

Thanks

coolio

I don't know anything about ebikekit, but I would make sure that that hub has those thicker spokes. That's a lot of heft that you're gonna carry.

timmythology

I fully confer coolio, and now I have also figured out that lights, and stereo can be powered through a 12v regulator?, so that got me to thinking I could run a rear mounted car camera instead of mirrors, and just have the monitor.

O and for the wheels, that is what the LBS is for. They will either approve of the job, or they will rebuild it. So that I can go on rides with Wally, and enjoy my bike.

Thanks for the concern though, and it is valid.

timmythology

Just a follow up.

Frame set is at the bike shop. With derailleurs and stem on order.

Ordered my e-kit today through ebay, and it can take up to six weeks for delivery, so I can hope for an arrival in 4 weeks.

Now for the really hard part of this process, waiting.

Guess ole' Jasper can have one last pedalpalooza before retirement.

I just wanted to follow up with some of the quick photos as a sign of appreciation for the information.





My ride home from the bike store, Seven Corners Cycle, was a blast. With the 1000w motor set at one, I was averaging 30 kph. I had to go with friction shifters and that is new for the rear gears. Getting ready for a longer ride tonight not real sure of length.

The twist shifter is something new to get use to, especially while spacing off at a light.

I loved the ride, I love the look, and I will have more pictures, and a video of the build after I process it.

Thanks for the assistance on this project.

I am now carfree yipppee kiyay
