I emailed Stromer asking for the supply values for the headlight circuit. I received a response saying that even if I found a different light that worked, installing it it would void the warranty. So I still don't even know whether the motherboard can supply sufficient voltage for one of the...

I'm planning a long trip this fall on my ST2 and wanted a second battery. A friend who is a grad student in the engineering department at a local university has built dozens of ebike batteries and has experience with and access to access to their battery welding and assembly equipment. I...

I bought a "Cool Change" (where do they come up with these names?) trunk bag on ebay for $50, and bought the racktime adapter for $30 including shipping from a German company on ebay as well. It works great. I also bought a pair of Seattle Sports Hydralite panniers. They seem to be...

Thanks as always Ravi. You are a fountain of ebike expertise and wisdom. Do you know where I can find the specs of the circuit for the ST2 headlight? The NIP 500 might be fine, but if the circuitry could supply enough current for the 800 I'll go that route. Someone somewhere must have the...

The Supernova light on my ST2 is insufficient for where I ride. I need something with a wider beam and a longer throw, preferably with a cutoff focus to avoid blinding oncoming traffic. I'm looking at the Seca 1800 which looks like it would do a better job, but without disassembling the bike I...

I understand that a lighter bike would be more nimble, but honestly one of the main appeals to me of ebikes is the fact that weight doesn't really matter that much. Traditional cyclists spend crazy money to get the lightest components possible because the weight slows them down. On an ebike...

Mike- As I mentioned up above, I had the same the same issue. I opted to do the repair myself. The most difficult part (by far!) is the removal and replacement of the plastic battery sleeve inside the battery door. The video on Youtube will be very helpful for your mechanic when he does the...

Here are a couple of great stories about theft recovery of Stromer ST2s using their built-in GPS system. The slick think about the Stromer GPS integration is that it part and parcel of what makes the bike function. It can't be disabled or removed without rendering the bike useless as an ebike...

Great post, Nic! I wish there was a way to unleash the full power of the ST2 motor. I usually ride between 22 and 26 MPH, but sometimes I wish the bike wouldn't cut off at 30. I live in a small town with lots of empty rural roads. It would be great to really push it on occasion.

I met with my LBS to talk about the upgrade. They suggested I wait a year. New wireless technology is just coming out, with Sram being the first to offer a wireless solution where the batteries for both the shifter and the derailleur incorporated into the components themselves. The shifter...

I've had my ST2 for only a few weeks and despite having to replace the motor control cable, I am as thrilled with the bike as any purchase I have ever made. However... I had a chance to ride an ST2s yesterday. Holy smokes. The shifting is on a whole other level. I never use the small...

I live in Essex Jct. but work in Colchester. It’s a very hilly 4.5 mile ride each way. The Stromer smooths out those hills really well. I assume you know that Johnson State College and Lyndon State College merged. Why they didn’t name the new university Lyndon Johnson is beyond me. I’d bet...

The replacement cable for my ST2 showed up today. I had the bike largely disassembled in preparation for the repair. Aside from the complete PITA of removing the screws that keep the plastic battery sleeve and motherboard in place, it was really simple. If the battery door could be removed it...

I've been wondering whether Stromer could offer what seems like should be a simple addition to the Omni/ app: allow level 1 to be customized like level 2. I have a 4.5 mile commute each morning and evening. Half is suburban residential roads and half is city with lots of hills. I have the...

I just got off the phone with Crazy Lenny's. They are sending the cable directly to me. They made it clear that it should probably be done by a certified Stromer repair center, but I think they might have to say that regarding any repair. There is a very good video on Youtube which shows the...

Don’t know about the riser stem, but I would bet anything that a manufacturer- maybe even Stromer themselves- will come out with an adapter or series of adapters to allow gadgets to be attached. Even if it’s only someone with a 3D printer and an Etsy account, if people will buy it, someone will...

It would have been a great story, but for the sequel. Sequels are never as good as the original, and this case the protagonist loses. It happened again. The motor began vibrating harshly every time I applied enough torque to engage the motor. Brake regen seems to cause it as well, though to...

Hey! Another Vermonter with an ST2! I'm in Essex Jct. Where are you?

I thought Stromer U.S. was on the East Coast. Lucky for me I am and they aren't. Sometimes that time difference is a really good thing. After work I called and spoke with a super helpful rep who thought it might be nothing more than a poorly seated motor control cable. I dropped the rear...

Thanks for the suggestion. I'll call Stromer in the morning. Right now I have work I didn't finish because I was out walking my bike.
