I bought from GRIN technologies and second the recommendations from the previous poster. They are a bunch of engineers and were very helpful in all aspects of the conversion of my Tern Verge Si8.

Yes I would like to see this for my battery as well. Great idea and maybe someone can construct one and sell it online.

This hold back that you talk about is something new to me. The newer Bosch motor (2019 Performance line plus) reviews mentions that it free pedals easier than previous models. I don't think its a "hold" back but just the resistance you are feeling once the bike reaches the max allowable speed...

They should add the belt drive to their Vektron and GSD models and then we'll have some appealing choices. I like the folding S10 but don't like anything to do with the chain. Add a belt...are they listening I wonder!

No place to put your stuff. Doesn't look like there are mounting points for any kind of rack. Fenders are too small for our rainy days of Vancouver weather. A fair weather, high speed rider, lots of style and no practicality. Sorry keeping my wallet closed.

I guess you could but that's not much of a worry if you have a front mounted motor. I would think you need a cut off with a mid mount motor because of the force that is applied as you are pedalling places some stress on the chain. Even if it's a rear mounted motor I don't think it is really a...

If you want to be practical, then look to the e-bikes with internal hubs and belt drives. All the chain drives require maintenance and can get sloppy with oil. If you are going to spend big bucks for a commuter, look at the Riese Mueller (R & M) bikes. Don't just shop because of "visually...

I would think they would have a battery level indicator, From what I remember with Court's review it did. So isn't that good enough? I just checked with their web page... Backlit LCD with Charge Indicator, Speedometer, Odometer, Trip Odometer, Pedal Assist Level, Wattmeter, and More

OK I have only had this for about a month and there are some really neat features that I like with Cycle Analyst. First and foremost, is it has lots of user inputs that you can adjust, define and just play with. GRIN has Windows and iMac software apps that you can use to adjust the Cycle...

I also had a clicking noise...It was the front brake. The housing was a tad close to the disc and would rub against it so loosened it off and cinched it up further so it ran with a bigger gap. Sometimes it also could be a worn out chain. One of the kinks could seize and not rotate as it moves...

BTW their site is very educational ....

Go to GRIN technologies...they have a number of controllers that run from about $130 to $450 (Can). They can sort out your wiring because they supply DIY parts for numerous motors (front and rear hub motors). So I would take some pictures of your cabling coming out of the 350 watt hub and the...

Who is BH??? Where do you live because in the GRIN's showroom there is a shelf of used parts and I saw some smaller G310 Bafang motors there. Go too Ebikes.ca and look at their products. Lots of choices for rear or front hub motors. They have a very informative site for those who like DIY.

Here is a summary of what I did to my Tern Verge Si8. Number one, the reason I did it because I really am sold on the Gate's belt drive - Shimano Alfina 8 speed hub: 1) Purchased the 20" laced Bafang G311 front hub motor, GRIN's Baserunner controller, GRIN's Cycle Analyst 3.14 dash board...

I have a Bafang G311 and you don't have to remove the spokes to service it. Thats my understanding. These hub motors are supposedly easy to repair. It has lots of seals to make them water resistant. GRIN technologies has a video on taking apart a Bafang hub motor. Looks easy to do with just...

OK Tern just released a belt drive e-bike named HSD. This is their first. However, its listed for $3699 (US) that's the second least expensive model but its still not quite a full folder. Just the steering stem folds down and the bike is a full 65 inches long. It looks a lot like the R&M...

Lets get picky here. Nm is Newton meters which is a measure of torque. The larger the number the more torque. The higher number is not necessarily a better number...this is not a value judgement or good or bad or happy or sad but a measurement of the twisting power of the motor.

Get yourself one of these...available from Amazon. Bike Tail Light, Built-in anti-theft & search system remote taillights, USB Rechargeable Taillights with 10 LED 120 lumens & 3 Light Mode Options & 100 meter Remote Control & 120 DB bells Waterproof Silicone and Condesigncealed , Suitable for...

I think Tern is going to be releasing their BYB product on that date .... July 9th. Product is going to be shipped to the dealerships and as much as I would like to see them update their S10 or even GSD line with belt drives and HUBs, their reasoning is simply because of the costs. There is a...

OK then we all have to wait until July 9th...a few more days and lets see what Tern has up their sleeves. I think with your Spot, if you wanted to add a motor to it, it would be done as an educational process. Its nice to learn about what is involved in the building of an electric bike. I...
