spybike seatpost tracker at a glance

Free Online Tracking Service

Should your bicycle be stolen, this vibration activated tracker will begin uploading its coordinates to our free online service. You can log into the Tracking page and see where your bicycle was taken.

Cheap to run

The tracker comes with a global prepay SIM. You can buy credit for that SIM card on our website at a cost of USD 5.00 per month. This includes 10 free SMS notifications and unlimited data traffic and emails. No contracts! You can also use your own SIM if you wish.


The tracker contains a very large 5000mAH rechargeable lithium battery and comes with a charging cable. The tracker can go for months between charges so long as you remember to disarm the tracker before riding your bike.

Bluetooth Pairing

The tracker pairs with your mobile phone. When it detects vibration it will check if your mobile phone is within range. If it is not, then it will assume it is being stolen and notify you and then begin uploading its position to our servers. You don’t need to arm/disarm the tracker, just carry your phone.

GSM fallback

Should your bicycle be inside a building it may not be able to obtain a GPS lock. In this case it will fall back to GSM positioning. This is less accurate but will give you an indication of where your bicycle is until it can obtain a better lock.


The seatpost tracker is housed in a normal looking seat post. If you are concerned at adding extra weight to your bicycle, you needn’t be. The seatpost tracker and battery only add a few hundred grams together.


Initial configuration is done by sending the tracker SMS text messages. Once installed, you should not need to send your tracker SMS messages again. It is activated using blue-toot pairing.


All of our products are covered by a 12 months manufacturer’s warranty in case of defects and a 30 day refund policy in case your tracker does not meet your requirements for any reason.


We can supply seatpost in the common 27.2mm size (31.6mm coming soon). Intermediate sizes can be fitted using a seatpost shim available from bicycles stores.

Frequently asked questions

Will the tracker work in my country?
All spybike products will work anywhere in the world there is a 2G GSM mobile network. It contains a quad-band GSM modem which means is will work in any 2G GSM network (including the USA). Link to wiki pages detailing supported countries.

But my SIM card is 3G. Will it work on my network?
Most networks are 3G+2G. There are some 3G-only networks but these are rare. Most of the main networks support 2G. If you use our SIM card that is supplied with the tracker then it can connect to multiple networks in most countries meaning you get better coverage.

I can get my position using whereareyou but I cant see my position online?
Please follow the step by step instructions for setting up your tracker for online tracking

What is the on-going monthly cost and how is it paid?
The tracker needs a SIM card so it can upload positions during tracking and send you warning SMS messages. We supply a global SIM card on a prepay basis for $4.50 / month that comes with the tracker. We recommend our SIM card since it is easier to configure, connects to multiple networks (better reception) and you can top it up online on our website. Since it is prepay you can buy as many or few months as you like (ie. You can protect your bike over summer if you wish). You can also use your own SIM card in which case there is no further charge.

What does the on-going monthly cost include?
The $4.50 a month includes 10 free SMS notifications, and unlimited data traffic and emails. This is more than sufficient for the use of your top cap tracker as an anti-theft device, since it does not send an SMS each time it uploads its coordinates to our database. This ONLY applies if you use our SIM card that comes with the tracker. If you choose to use your own SIM card then you will need to pay for this with your network provider.

Can I use my tracker to track my bicycle rides?
In theory, yes you can use the top cap tracker to trace your routes when cycling, but you should be mindful that the battery would need charging much more regularly than if it was solely being used as an anti-theft device. (It may be easier to use a free/inexpensive mobile app to tracker your rides.)

Do you deliver to my country?
Yes – we deliver anywhere in the world. Shipping is a flat rate fee of 8 USD so the shipping cost is the same for any country.

Do you have my seatpost size?
We can supply seatpost in the common 27.2mm and 31.6mm sizes. Intermediate sizes can be fitted using a seatpost shim available from bicycles stores.

Who typically uses Spybike devices?
We have a good mix of customers, both consumers and law enforcement agencies using the Spybike products. Often consumers come to us when they have had a bicycle stolen in the past and are keen to be able to do something proactive should it happen again. Spybike products have also been used by various law enforcement agencies throughout the world. We have received excellent feedback over the years.
