I was agreeing with you, but mistook the double kickstand you linked as a one piece(both legs are one rigid piece).

no sweat I likeyorus better it gets out of the way mine hangs below the chain I have had the chain get caught in it when backing our tandem out of the garage. but it is sure steady.

Hello Ravi,
Just curious, why your cargo bikes are not belt drive with IGH ?
From my experience, I don't really care much about belt drive but I'd prefer at at least single speed chain or 3 speed IGH with chain.
I have had many bad experiences with derailleurs and I don't like them generally.
Ebikes don't really need many gears/ gear ranges. 3 gears are enough I think for most people.
Thanks,

Hi there,
The current Cargo bikes are built for a particular client in Canada.
Generally, once you go with a mid-drive and belt, the costs tend to go up and the market in the US not matured enough for high volumes of belt-drive Cargo bikes. We actually designed a belt-drive Cargo bike first and it was costing us $0.5M to order small quantity of those but we chose to use the money to build the battery technology. Were you looking for a belt-drive cargo bike? hypothetically, how much would you pay for such a bike?

Hi Ravi,
I have had bad experiences with derailleurs so a mid drive, IGH with China is good for me. I don't really care much about belt drive but IGH with chain is what I want. ~$3K USD if i buy a cargo ebike.

Thanks for this note.
We did close an investment round, and we are setting up a battery manufacturing facility in Canada. I was in Asia as part of the Canadian Cleantech delegation, and we received very positive responses. Here are some pictures from our Trip to Asia - India in particular.

We are testing a new full suspension eMTB model that will be released later this Spring in limited quantities.
This one has 625Whr Bosch battery, Bosch Gen-4 speed motor and FOX front and rear suspensions 160mm travel.

We received a request from a client who runs tours and rentals for a comfortable, step-thru full-suspension bike that could handle off-road trails and be outfitted with a rear rack and fenders. They are receiving about 50 E-bikes from us. We will be doing a thorough QC on everything.
This bike comes with
This bike comes with
- 750W Bafang Ultra motor,
- 52V,20Ah pack tested to UL standards
- 4-piston brakes with E-cutoff from Tektro
- 27.5" wheels and 2.4" / 2.8" tires from Schwalbe
- and RockShox front and rear suspensions
- Currently, we are strengthening some rear rack designs

Hi Ravi
I've been PM'ing you about the Shakti for my wife and my wife happened to see this photo while I was looking at it. She likes the look of the bike (with added fenders and rack).
Will it come with a throttle and will there be more than one size?
thanks
Ron

That's no problem, Ron!
A few units arriving by early May are 19" in size and customizing with rear rack and fenders is not a problem.
The ones that are landing sometime in mid-June are 17" and 19". Let us know how we can help.

What do you guys think of this suspended rear rack design? of course the fenders would be added for urban usage.
Any thoughts on suspended vs un-suspended designs?

Definitely suspended. Attaching a loaded rear rack directly to the rear swingarm seems like a recipe for bad handling. What do you think the weight limit on this design would be?
Secondary question - I love the way the bike looks, but isn't this design essentially a single pivot, meaning there isn't really a way to control the leverage curve? Maybe I'm missing something not visible in the photos.

The weight limit is 25kg ( 55 lbs) as of now and we believe that is sufficient for most folks. What do you think?

I think that'd be great! I think the R&M SuperDelite has a 20kg capacity.
(Sorry, I edited my earlier post with another question on suspension design while you were responding)

Single pivots designs are low-maintenance and often more than enough for light off-road. You need horst-link or multi-pivot for eMTBs.
You may also notice, R&M have this single pivot design on their Superdelite, Load and a few other models.
The bike we are developing is more for urban usage (read potholes etc.) than MTB setting and using a MTB-suspension design makes it more expensive and most often such a design is wasted because people don't really make use of it.

Other features:
- A throttle (very important for a lot of people)
- Integrated lights (1000 lumen front, rear light) and rear rack.
- Longer fenders, slightly curved handlebars,
- suspension seatpost and the gusset near the motor would be nicer looking.
